Supernova remnant CTB1 received additional light

29.12. Tapio Lahtinen decided to shed more light on the supernova remnant CTB1 he described two years ago. "I photographed the subject for the first time in 2018, but 11 hours of exposure didn't bring out the subject very well. So I decided to shoot more," says Lahtinen, who used the remote telescope in Fregenal de la Sierra, Spain. Now the exposure is a total of 28 hours and the difference from the previous version is clear.

Planetary Encounters - Successes on Christmas Eve

24.12. Three days after the maximum of the great conjunction, the clear ruptured at dusk, mainly in the direction of Turku. One cloud gap observation is from the east of Mäntyharju. As of this writing, eight enthusiasts have managed to report pictorial observations of the conjunction of Jupiter and Saturn on Christmas Eve. The planets are still relatively close to each other in the last days of December. (Photo by Lasse Nurminen)

Jupiter and Saturn were covered behind the clouds

21.12. The maximum of the great conjunction in 2020 seems to have been covered by clouds in practically all of Finland. At least so far, on the evening of the 21st, no successful observations have been received from the domestic crust. The last time the clouds receded in part of Finland was on December 17, and the observations of the evening include Joni Virtanen's view of Kokkola. 

Enthusiasts described the asteroid Ryugu

18.12. On December 6, the Japanese Hayabusa2 probe dropped an Australian sample of the asteroid Ryugu. Kari Laihia and Toni Veikkolainen have now uploaded to Vahti pictures of this asteroid the day after the arrival of the sample capsule. A kilometer-sized Ryugy was 0.075au away from us at the time, observers say. This is 11.2 million kilometers. The closest Ryugu will be on December 29, 9.1 million kilometers away.

Rare view of Mare Orientale

14.12. Antti Taskinen got a picture of Mare Orientale that hit the button. The center of the sea is at 95 ° west longitude, which is why it is normally hidden behind the edge of the Moon. However, due to the libra of the moon, the Mare Orientale can be spotted from Earth from time to time. "The circumstances are right, luck is quite a lot here too," Taskinen commented on his observation.

Deep sky in early December

13.12. Here is a collection of images of the deep sky that appeared in December. Top left in Ari Jokinen's exposure IC 342 aka The Hidden Galaxy. The object gets its name from hiding behind the equator material of our own galaxy. Below it is Vesa Vauhkonen's print of the Horse's Head Nebula. The views on the right are from Erik Pirtala's last three-image publication. Above is the supernova remnant IC443, i.e. Jellyfish Nebula, below NGC 7023, The Iris Nebula.

Comet C / 2020 M3 wanders in the sky

12.12. Pasi Äkräs found an extra vibe in the images of the deep sky he had exposed a few nights ago. “I blinked at my pictures in the morning and noticed movement in the corner of the pictures,” Äkräs writes. There is a comet C / 2020 M3 (ATLAS). The animation has 20 consecutive 10-minute exposures. Jorma Ryske informed in the comments of the observation that the filter used in the description shows the comet's dust tail without the light of its gases.

Soul fog in two night exposures

11.12. This time, Westerhout 5, or Soul Nebula, is the object of deep sky. It was photographed by Ville Miettinen in Varkaus on two nights now during December. "There are many great details in Soul Mist that came to light with the new telescope," Miettinen writes. A total of 14 hours was accumulated for the exposed image. The object found in the constellation Cassiopeia is 6,500 light-years away.

Two fireballs on Tuesday

10.12. There have been many sightings of the two fireballs seen on Tuesday. The first was seen in the evening a couple of minutes before six, the second at 11:56 p.m. Even at a later date, there are far fewer observations of the latter, but unlike the previous car of the evening, this was also captured with fireball cameras. Above is Markku Lintinen's picture of Kangasala. A single car observation has also been reported at 20.02.

Two streak stars from Varkaus

9.12. At the Härkämäki Observatory in Varkaus, on the night of December 7/8, an anonymous enthusiast decided to take streak photos. The view and imprint was spectacular. “In the morning, after a small session of admiration for planetary nebulae, there was then still plenty of time for another image whose slightly more abstract foreground was the red-lit dome of the first tower,” the photographer writes.

Waiting for pearl clouds

6.12. The mid-winter special clouds, pearls, have not yet tolerated appearing. But no worries. Although in Vahti's statistics up to 2011 the start of the pearl season started on November 27 at the earliest, the latest ones have been made until January 29. These extremes were experienced last winter and winter 2012/13, respectively. Here’s a record-breaking amount of spending last season, Thomas Kastin’s photo 31.12. From Enontekiö.

Recent deep sky releases

29.11. Here is a selection of Deep Sky items that have recently come to Sky Watch. At the top left is Jari Kankaanpää's picture of Rosette mist. Next to it are the nebulae of the constellation of Orion in a sample by Tomi Kurri. At the bottom left is the Pickering Triangle, part of the supernova remnant in the constellation Swan. This is one of three sites that Erik Pirtala just published. And last on the bottom right is the Andromeda galaxy in Jussi Koponen's picture.

A violent halo play in Sotkamo

26.11. Yesterday in Sotkamo a really hard class was stabbed. The images taken by Sami Härmä from around the sky show a lot of rarities, such as the Ounasvaara arch, of which less than ten observations are known worldwide. The raw images in the play are still awaiting processing, which may continue the rarity list. The pictures show references to the Borglängen arch, the only known sighting of which is from a neighboring country two years ago.

Milky Way in the autumn pictures

22.11. During the autumn, a lot of great pictures of the Milky Way have come to the Skywarden. Let's take two examples. On the right, a composition by Pirjo Koski with a sky observer in Pyhäranta on 19 September. On the left, Sari Pietikäinen's wooden silhouette interpretation on November 9 in Rovaniemi. "I got good tips for adjusting the picture, and this is now the result of two evenings of adjusting and training," says Pietikäinen.

Comets, comets

17.11. After a little digging, there are comets in the sky other than the current favorite ATLAS. Here are all the other six comets photographed by enthusiasts in October-November. From the top left: C / 2019 K7 (Smith) , C / 2018 N2 (ASASSN) , 29P / (Schwassmann-Wachmann) . From bottom left: C / 2020 S3 (Erasmus) , C / 2019 U6 (Lemmon) , 156 / Russell-LINEAR .

Two fresh views of the Triangle Galaxy

15.11. Erik Pirtala and Antti Taskinen took advantage of the recent clear nights to describe the M33 of the Triangle constellation. Taskinen, whose picture is on the right, got usable exposure in a pile for three hours. For Pirtala, light from this galaxy of the local group of the Milky Way accumulated for a total of 10.5 hours. "Fast f / 4 optics and dark moonless nights in a very dark place in Härkämäki produced very high quality data," he writes.

Comet Atlas is now at its best

12.11. Several enthusiasts have photographed the comet C / 2020 M3 (ATLAS), which is visible in the constellation Orion. The destination is now projected to be brighter. Here is a picture of Harri Kiiskinen , the comet is a green fog ball on the right. At the bottom, Orion's gas mist M42 is shining. The brightness of the comet is 8 magnitudes, so without aids it cannot be seen.

The moon got color

10.11. Jarmo Ruuth's picture shows the Moon, but it has something different: a spectrum of colors. The method was simple. “Color saturation has been radically increased,” says Ruuth. “I’m not claiming now that the moon is actually colored, but a bit like the images of a deep sky can be found when you dig right,” Ruuth writes.

Sweden's stunning fireball was also visible from Finland

7.11. The big fireball that woke Sweden before midnight was also visible in Finland. The case has become more than a dozen domestic reports. More observations are hoped for on the fireball form . The fireball remained at least in the meteor cameras of Ursa in Tampere and Sirius in Jyväskylä. The event was covered by Stars and Space and Iltalehti .

The object of the southern sky: the sculptor's galaxy

4.11. With his telescope, Jari Saukkonen photographed the Sculptor's galaxy, which is one of the brightest galaxies in the southern sky. The observation site was remote in Rio Hurtado, Chile. The sculptor is a star-forming galaxy that generates a lot of stars. According to Saukkonen, many of the red dots in the image are not stars, but galaxies whose fading speed has colored them red.

Recent planet views

27.10. This time, the Planet Gallery has three objects photographed in October. In the middle of Mars, which has been popular this fall because of its proximity to Earth. "One of the best seeings of the autumn," commented Jerry Jantunen , who took the picture, in Helsinki's Kaivopuisto. Jantunen's shot is also on the left, this is Venus. The small blue ball on the right, in turn, is Lasse Ekblom’s Napsu from far farther Neptune.

A fork was visible opposite the sun

26.10. In Lahti yesterday, a two-pronged fork-shaped pattern was seen directly opposite the Sun. It is a combination of two rare halo phenomena, Tricker and diffuse counter-solar arc. In the picture above, the observer, Reima Eresmaa , has stacked five individual samples, thus highlighting the phenomenon even better. In the upper clouds, these counter-solar arcs are a rarely seen treat. Other rarities were also on display.

Northern lights conjured up a spectacular SAR arc

25.10. The red SAR arc was a topic of conversation when enthusiasts put their pictures on Sky Watch 23/24. from the great northern lights show of the night. Above from the left, photos by Heidi Rikala , Eero Karvinen and Minna Hintsala of this rare form of northern lights that began to brighten in the sky towards the end of the main screening. The weather was favorable for the sky shake roughly south of the line from Kokkola to Juva.

The ice age began in Ylläs

24.10. Iweta Seppänen's photos from Ylläs started the ice mist season on Wednesday 21.10. The start is at the earliest end in the Sky Watch statistics. The record seems to be held by Toivo Säkkinen's 2009 observation outside Vahti in Kuusamo on 14 October. There may be previous cases as well, as snow cannons will be launched in the north at least at the turn of September-October.

Peaceful wishing in October

21.10. October has been a year for the lifts. Halof days have been rare due to lower cloud cover and nothing significant has been seen when the window has opened. The day before yesterday in Turku, Mikko Peussa was cheered up by this slightly higher-quality 22 ring, which is a more familiar basic rink. The day before, Anu Tossavainen also admired a great 22 tires in Rovaniemi. Now we are just waiting for the first ice fogs from the north.

Bubble mist in the constellation of Cassiopeia

17.10. Antti-Jussi Pyykkönen published a picture of the Bubble Nebula visible in the constellation Kassiopeia. This seven-light-year cosmic bubble is about 7,000 light-years away from us. The bubble is formed when the wind blown by the hot star inside it collides with the surrounding colder gas. Pyykkönen's sample comprises exposure for a total of 23 hours.

The peak of the reflection rainbow was photographed

14.10. Rare reflective rainbows are almost always seen at the edges. We have been able to admire photos from abroad of the reflection rainbows visible in their law, and now this miracle has also been spotted in Finland, thanks to the photos taken by Aija Heikkilä and Tatu Rentola in Jyväskylä yesterday. Above is a picture of Rentola with the lower main rainbow, then the weaker side rainbow, and the stronger reflection main rainbow at the top.

Unusual - the peak of the reflection rainbow was photographed

14.10. Rare reflective rainbows are almost always seen at the edges. We have been able to admire photos from abroad of the reflection rainbows that appear in their law, and now this wonder has also been spotted in Finland, thanks to the photos taken by Aija Heikkilä and Tatu Rentola in Jyväskylä yesterday. "Not a bad day at all," writes Heikkilä, whose image has a reflective rainbow extending beyond the law point marked with an arrow.

The brightness curve of hot Jupiter

9.10. There are no eye-catching images of exoplanets, so it is sufficient to measure light. Harri Kiiskinen sacrificed an observation night for our exo HAT-P-1b 521 light-years away. A curve based on over 400 images beautifully reveals how the planet’s passage dims the parent star. "We succeeded beyond expectations," says Kiiskinen about his new conquest. The planet is the size of Jupiter and orbits near its star in a 4.5-day orbit.

Heart mist and its igniting giant stars

7.10. "Two good evenings were spent filming the heart area of the Heart Nebula," says Jaakko Asikainen of the picture he took, which comprises a total of 10.7 hours of exposure. "The first night I took a mere hydrogen narrowband and the second night I photographed luminance and colors." Also pictured is the open constellation Melotte 15, whose radiation from young and bright supergiants illuminates the fog.

Mars glow in the pictures

3.10. Top-quality seeings have allowed enthusiasts to take top photos of Mars, while the Earth is getting closer to the planet and will be closest on October 6th to the next 15 years. On the left are fresh style samples by Ari Haavisto and on the right by Jerry Jantunen. "There was so much good weather in Ursa's tower that I haven't seen anything like it every year," says Jantunen.

Yöllisiä sumukaaria

2.10. Towards the beginning of October, the landscape has been foggy often. Yet the fog arc has become relatively few observations. Markku Ruonala corrected the situation the other night by photographing a fog arc glistening in the light of this Moon in Aka. Likewise, on the same night, Heidi Rikala in Ikaalinen Sisätö was on the move.

There was cumin in the fireball on Tuesday

1.10. Tuesday 29.9. at 00.57 a car flew in the sky, which was also accompanied by sound observations. Lasse Heimala , whose picture is on Luumäki above, writes that about 30 seconds after the fireball was seen, there was a distant tumtumtum sound. Jukka Kytömäki, who also saw Bolid on Mäntyharju, says that he heard a fall from the sky in 2½ minutes. It is entirely possible that the fireball has been behind the sound. Time estimates are easily thrown.

A living strip of zodiac light caught the images

27.9. The Milky Way must be visible in Pekka Parviainen's fisheye photo on the morning of September 20th. However, attention is drawn to the weak solder that curves between 5 and 10 p.m. It is rarely described as an extension of the zodiac light, the "zodiac ribbon." The brightness from which the tape begins at 5 a.m., gegenschein, is also not quite an ordinary catch. "The time of the wine glass," says Parviainen, who found two more cases in his archive. Matti Helin has also photographed these.

The northern lights sky provided a rarer SAR arc

25.9. The red and stable SAR arc grabbed the cameras of the celestial photographers on the night of September 23-24. To the right is Petri Sallinen's box of this lesser-seen form of northern lights in Juuka. On the left is an image of the automatic camera of Sirius Hankasalmi Observatory in Jyväskylä. Exactly how the SAR arc is formed is not yet completely clear to researchers. There are sixteen observations of it in Taivaanvahti since 2015.

Excerpts from a recent lullaby

24.9. In northern Finland 17.9. was a great halo day, on the right Mika Aho's picture from Pallas. Further south we got a good period 20-22.9. Rarities were seen every day, with prey including the Wegener Counter-Sun Arc, the Tape Arc, 120 Side Sun and the Counter-Sun. On the left 21.9. Tero Laine's picture of Heinola. And in the middle of the coming ice mist winter, there are artificial light pillars in the lower cloud. The picture was taken by Heidi Vierimaa in Kalajoki on 22.9.

Less commonly described: Two months of Mars

23.9. Mars is a popular destination, but its moons of Phobo and Deimo have been seen much less in the pictures. In fact , the shots Lasse Ekblom received on September 15 are the first in Sky Watch. Two of Ekblom's four-image series have been selected above. The outer Deimos is visible in both, the inner Phobos only on the right. “I had to take a longer series, but the clouds finally rolled over after 3n,” writes Ekblom.

In long exposure dark fog vdB 9

21.9. Erik Pirtala says that he has decided to shoot his first dark fog this autumn. The target was vdB 9 of the constellation of Cassiopeia, whose nicknames include Helping Hand and Cosmic Hand. The exposure accumulated on the subject for a total of 14h 44min. “It was a difficult target indeed, but in general I am quite satisfied,” writes Pirtala.

Good Bishop ring in Juva

19.9. A wide and light-colored Bishop's ring can easily go unnoticed in the daylight if you don't know how to look left. Bishoppi is especially visible in the picture taken by Petri Martikainen at Juva yesterday. Inside this largest known circumferential phenomenon is a blue disc surrounded by a wide reddish ring. The image is stacked from 20 individual frames, which smoothed out the cloud background and brought out the phenomenon better.

Stereo couples from Moon

18.9. Pekka Parviainen has presented stereo photos of our traveler. The depth effect is created when the images glide on top of each other while staring at them. Stereo pair images allow the moon to wobble, to vibrate. Thanks to it, the surface of the Moon is visible at different times from a slightly different direction, at a maximum of about 7 degrees. It is a slow event and Parviainen's picture pairs are usually from different years.

Northern lights in early autumn

17.9. There have been several northern lights in September, modeled on Jani Päiväniemi's picture from the first hour of the 14th in Kuusamo. Specialties were also available. The next night in Enontekiö, Timo Oksanen's picture seemed to have a "slatted fence" structure related to the Steve northern lights arc found in 2016. Instead, the rays seen in Tommy Lågland's sample seem like an air glow, although they resemble the dune-northern lights found by Finns in 2015.

Deep sky: subject to less described Sh2-119

15.9. A few degrees from the much-described North American nebula is the emission nebula Sh2-119 in the constellation of Swan. It was taken over by Erik Pirtala in Varkaus. “For three weeks, I was able to collect 19 hours of light at this rare site,” says Pirtala. Other recent targets include the nearby M33 galaxy photographed by Ari Jokinen and the North American nebula aimed at Kari Kauppinen and Vesa Vauhkonen.

Ending cycle of the Moon in close-ups

13.9. Highlights recent observations focusing on the details of a favorite destination on the Moon. The model is a good old pen and paper, ie Jari Kuula's drawing of the area of our traveler bathing in the evening lighting. With the cameras, the Moon was zoomed by Lasse Ekblom and Martti Koskimo . "Usually, the effective observation time is 1.5 hours before the dripping frosts interfere," says Koskimo about the problems of filming on the lawn.

Just a great halo day on Friday

12.9. Halov 2020 has not been strange, so the more abundant table setting in the sky seen yesterday was a welcome cheer. Observations were obtained from Turku to Rovaniemi , with better goods visible from the Jyväskylä level upwards. The rarest halo found in Olli Sälevä's and Vesa Särkelä's pictures was Wegener's counter-solar arc. "Sometimes there were quite symmetrical and sometimes very one-sided halos in the sky," writes Särkelä, whose picture above.

The water statue crowned the dawn in Jurmo

10.9. Last summer, several good pictures of water columns have been taken, but in Heli Toivonen's shots on August 29. Jurmo's dawn has a special picturesque atmosphere. "It was set to ring 20 minutes before sunrise, in the hopes of seeing the sun rise from the sea," says Toivonen, who was spending his weekend at the end of the cottage season. The water statue was visible for a total of 15 minutes. "The most special sunrise in my life," says Toivonen.

Long lasting fireball on Monday

9.9. Observations were received from Utsjoki to Tampere about the slow fireball seen on Monday at 11.03 pm. "The majestic slow scratching of the atmosphere," writes Markku Lintinen , whose camera in Tampere shows a car for 19 seconds. In Kiimingi with Pekka Kangas' camera (picture above), it stands out for as much as 26 seconds. There was enough time that in Oulu Dennis Lehtonen even managed to take a phone from his pocket to photograph a fireball.

Final report of the night cloud season

3.9. It is probably safe to say that the night clouds will no longer be seen this year. The season ended on the night of August 19/20, which bypasses the latest date in Vahti's statistics in 2012. The start on the night of May 22/23 was among the earliest in observations reaching eight years later, but the trip was still in the 2013 record, when it started on 12 / 13.5 nights. Above is Satu Juvonen's picture of this season's farewell show.

A special piece accompanied by rainbows

2.9. Pekka Huttunen published photos of an unusual rainbow play in Vieremä two days ago. “Only a small piece is visible from one rainbow, just as if the piece were sliding from right to left,” he writes. The piece turned out to be an exceptionally tightly limited reflection rainbow. Its continuum to the right, in turn, is a reflected ray of cloud. These rare phenomena arise when sunlight is reflected from water.

Mars has now been described a lot

1.9. Rising high in the sky, Mars has prompted more and more enthusiasts to bring out the imaging equipment. "After all, there is a huge difference in the quality of the image when Mars gets there from the horizon well above 30 degrees," says Jussi Saarivirta , who took the picture on the right on the night of August 28/29. On the left is the next night's Mars style sample from Ari Haavisto and in the middle is a sample from Jerry Jantunen more than a week earlier.

Two nocturnal water columns on Siikajoki

29.8. Water columns have been photographed extensively this summer, but less often in the dark, as in this sample by Jari Ylioja. At midnight 25 / 26.8. in the picture taken, the beautiful clouds illuminated by lightning grab attention, but looking more closely at the horizon orange against the sky stands out as a bonus two distant water columns. The variation of the phenomenon extending to the surface of water is called the water column, the thrombus extending to the surface of the earth.

Deep sky subject to Pelican Mist

28.8. As the night sky darkens, there have also been very observation windows available towards the end of August. Harri Kiiskinen targeted Pelican Mist at the beginning of the season, which he said would fit properly in the image field of the equipment. The result was a spectacular mark. "After the normal initial difficulties of the autumn, the technology played flawlessly," says Kiiskinen. Pelican fog is found next to Deneb, the main star of the Swan constellation.

Four rainbows in the same picture

26.8. There are already very good observations of the third and fourth rainbows visible in the direction of the sun. The picture taken by Petri Martikainen yesterday is unique in that, for the first time, all four arches have fit into the same portrait. The 5th and 6th rainbows have also been modeled on Les Cowley’s side. From the former, which can be seen inside the side rainbow, there are also possible observations from the world. Maybe these will be available in Finland as well?

The satellite was left without a name

22.8. Sometimes this happens: a satellite flying in the starry sky remains unidentified. Kari Kaila photographed on 17.8. Lyra's tire fog and the streak left by the satellite also came along. The body must have been far away, as it moved only 336 arcseconds during the 20-second exposure, which is about one-sixth of the diameter of the Moon. “I can’t identify the target even with Calsky,” Kaila writes. At least for now, the song is untitled.

The northern lights season is beginning, the night cloud is coming to an end

19.8. The photo taken by Thomas Kast on the shores of Lake Oulujärvi last night bundles the seasonal stages of two phenomena: northern lights rise, night clouds recede. "The small-scale but long-awaited show started," says Terhi Törmälä from Lappeenranta regarding the previous ones. In the previous nine years, the night clouds have only been seen further than now - in 2012, the season ended one night later. Maybe that limit will still be broken in the coming nights?

A handsome fireball was visible in southern Finland

17.8. Observations of the green fireball seen on Monday at 1:47 a.m. were obtained from the south shore to Lake Siilinjärvi . Brightness estimates ranged from Venus to a brighter full moon brighter. In Espoo, Mikko Allonen was initially the back of a fireball, but its brightness made him turn around. The image catch is the recordings of both automatic cameras and SLR cameras of enthusiasts who monitor at night. Above is a lucky shot by Jaakko Muukkonen.

Probable observation of a very rare 28 tires

17.8. The diligent stacking of halo plays rewarded Petri Martikainen the day before yesterday: the play seen in Juva seems to have a matte 28 ring. This is the first time that signs of halo rarity are seen in Finland in a celestial play. "This was an amazing thing, when with the naked eye it didn't look right at all. It's worth describing the stacks," Martikainen writes. Previously, the halo has been photographed on snow in Finland.

The clouds were the most troublesome of the Persians

14.8. The two best nights in the Perseid star flight flock between 11 and 13 August were overshadowed by clouds. More observations came from the previous nights. As a model, here is one of the three asses Jari Virtanen, who was on duty in Lohja, grabbed the camera 10/11. at night. "I had expected about 20 meteors for three hours, but the end result was only 8 meteors," writes Virtanen of the starbursts he saw. Perseids fade away completely 24.8.

The fog of soul opened the autumn of the deep sky

10.8. Autumn is approaching and the night sky is darkening at a good pace. Jussi Saarivirta decided to test his new tripod and with it he started the deep sky in the Finnish season in Vahti. On top of the three-hour material, the following picture was created, which is the subject of Soul Mist, catalog name IC 1848.

How far are there enough night clouds this year?

7.8. In August, the night cloud season has already turned to evening, but in the light of the statistics, there is still a week or two to go. In Sky Watch, the observations will last until 2011 and the earliest season ended on the night of August 12th and 13th in 2013. The highest was reached in 2012. At that time, the final show was on the night of August 19th and 20th. How are you this year? Above are the fresh nights on the horizon of Kalajoki described by Jarkko Alatalo.

A flame on the right rose from the sun

1.8. A handful of enthusiasts were vigilant yesterday when there was a gas eruption in the Sun. "A decent megalieska for a long time," writes Santeri Peltola , whose picture is above. Timo Inkinen was also satisfied: "There was a feeling that I was in the right place at the right time for once". Harri Kiiskinen, who also described the eruption, said that the protuberance was about 180,000 kilometers high. This is almost half the journey between the Earth and the Moon.

Three planets on a summer night

28.7. The nights get dark and the stars in the starry sky begin to become more noticeable. Tapio Lahtinen picked up the planets of the cavalcade at night in Tampere. In the portraits, the following outer planets Mars, Jupiter, and Saturn shine through us, combined here in the same image. The latter two were low on the horizon, making them less distinguishable in detail.

Sunspot finally visible

26.7. Enthusiasts have noticed the comma AR 2767 that appeared in the Sun in recent days. The comma may be a sign that the Sun's minimum has passed and the rise to a new maximum has begun. Above is Harri Kiiskinen's picture of a comma. "Hopefully the Sun's activity will gradually start to increase, for a long time only a flat expressionless disc has been available," writes Kiiskinen.

The double rainbow did its best in Kouvola

22.7. The rainbow show observed by Rauni Pakkala in Kouvola yesterday represents the absolute peak of Taivaanvahti. While bright main-to-horizon main rainbows have been photographed before, the Kouvola show is crowned by an equally long, exceptionally strong side rainbow. “The really bright rainbow and side rainbow didn’t fit the whole picture, so I made a panorama of six verticals,” Pakkala explains the technical side.

Rare pyramid fish in Juva

22.7. Recently, halo rarities have mainly focused on Juva, where Petri Martikainen has snapped halos born of pyramidal crystals. Above is a play from last Saturday that draws attention to the Double Ring: the outer is a 24-sided arc and the observation is the first on watch in more than two years. The next day, the taste for rarities was also reached elsewhere, when Wegener's counter-solar arch was photographed in Parais and Taivassalo.

Night clouds at a good pace

19.7. There is an excellent summer going on in terms of night clouds. "It would be good to get to sleep somewhere," says Terhi Virjonen, who has been monitoring the night clouds for almost two weeks. Even to their detriment, they have been: the comet NEOWISE has been more difficult to distinguish. As a choice of pictures of Mikko Lönnberg's catch from another night in Pori. “In the end, though, there’s nothing breathtaking about the screen, but it’s always nice to watch these on a summer night,” says Lönnberg.

Summer avalanche clouds in the pictures of enthusiasts

15.7. Let’s set the stage for avalanche clouds, whose menacing-looking revelations have been the subject of several observations over the summer. Here is an example of the case seen by Jari Ylioja in Kalajoki three days ago. “Otherwise, the miserable day was crowned by a great avalanche,” says Ylioja in his observation. Avalanche clouds are associated with thunderstorms and their passage is often accompanied by strong gusty winds. The weaker subspecies of avalanches, the roller cloud, occurs separately from the parent cloud.

Thrombi have been seen in abundance

13.7. An extraordinary avalanche of thrombus sightings has come to the skies in recent days. Here are two pictures from a video taken by Liisa-Marja Lentonen in Loimaa's Mellilä the day before yesterday. The movement of the rotating cloud statue is clearly seen in the video. "Yes, it really started to scare me," Lentonen writes. In the comments, Esa Palmi knew that it was not a thrombus created in the supercell thunderstorm, but in the wind meeting area.

Tail star on a summer night

8.7. Enthusiasts have managed to aim for the NEOWISE comet, a challenging target in the bright night sky. One of the comet’s bongans is Antoine Chauveau , whose photo above is above. “The head of the comet and even a little tail were visible with binoculars as the clouds appropriately receded during the darkest part of the night,” Chauveau writes. The brightness of NEOWISE is predicted to be already declining, but on the other hand, the darkening nights compensate for the dimming.

Rainbows, rainbows

7.7. In the midst of heavy rains, the Sun has peeked, and pictures of rainbows have been received in Taivaanvahti in recent days. The best issue was on the fifth of July, when several observers in Central Finland saw a great sunset rainbow. The example above is a sample of Petri Nurkka-Tuorila in Pielavesi . In Kuusamo's Käylä, Jani Päiväniemi raised the drone to photograph the rainbow seen on the horizon in the afternoon.

The night clouds are getting better

6.7. Half a dozen observers watched in the wee hours of the Fourth of July as the highest quality night clouds of the summer glowed in the sky. Above is the balcony view of Samuli Ikäheimo from the clouds in Lahti at half past two. The best time of night cloud is still ahead, they are typically observed until around mid-August.

The first water statue of the summer seen

1.7. Kustavi showed a thrombus at sea yesterday, the above-water version of which can also be called a water statue. This is an early observation of a water column in the Sky Watch. Typically, they have only been visible since late July. "By the beginning of the observation, the funnel coming from the cloud was very clear; when the picture was taken, on 20.04, unfortunately, it had already clearly started to shrink," says the observer of the phenomenon.

Thunderstorms

30.6 . Towards the end of the hot weather period, thunderstorms began all over Finland and people photographed lightning and handsome cloud formations. Above is Jari Ylioja's picture of thunderstorm-related mammoths on June 26 in Kruununpyy. "The first cell of the morning did not produce lightning much other than in the middle of the rain. However, the mammoths were spectacular," writes Ylioja.

Peripheral phenomena in the algal membrane

24.6. Lasse Nurmer finally succeeded in hunting the algae phenomena seen in the puddles. "I tried to apply for the same puddles last year, but I guess I was always there at the wrong time," writes Nurminen in his observation yesterday. These perimeters are caused by unicellular Nautococcus algae and Nurminen's samples represent the absolute best of the phenomenon. Two days earlier, Pentti Arpalahti described the phenomenon of Chromophyton.

Halo rarity in Muonio

23.6. In Taivaanvahti, Heikki Kainulainen published his observation of the reflection-sub-sun in Muonio almost a month ago. This very rare halo is visible as a pillar of light in front of the clouds. It is created when sunlight is reflected from water. In some cases, such as this one, reflection from the ice is also possible. The first-ever observation of the reflected sub-sun was made in the autumn of 1998 in Oulu.

Venus went behind the moon

20.6. The moon covered Venus on Friday just before noon. The above is an event in Helsinki to observe Dennis Lehtonen style displayed. "I had a very positive feeling from today and am happy with the pictures I got," Lehtonen sums up. Likewise, in the metropolitan area, the occult of Venus was noticed by Antoine Chauveau , whose video shows the coverage in its entirety.

Thursday thunderstorms and lightning

19.6. Yesterday thunder was served in the southern parts of the country and the storm bongars were ready with their cameras. "The set was amazing," writes Petri Nurkka-Tuorila about the lightning he saw in Espoo. Above is a picture taken by Ben Kalland of a lightning strike just 500 meters away at 3.20 on the Porkkala peninsula . “The front came in the morning from the open sea to the coast,” Kalland says in his observation.

Fabrics in Kustavi

18.6. Pekka Parviainen has woven fabrics on the seaside cliff in Kustavi. "One canvas watch morning was worth skipping due to excessive wind, but then the sun offered better-than-average distortions," Parviainen writes about the situation in the pictures shown above on June 13th. Two days earlier, however, the weaving raised the Sun for another 26 minutes after its official landing time.

Reddish rainbows

9.6. The rains have brought Sky Watch photos of the rainbow. Several of these have been photographed late in the evening, which shades the Rainbows red to suit the color of the low Sun. Above is the evening atmosphere of Eva Larzén-Östermark from the Åland Islands in Parainen . In Petri Martikainen's picture of Juva , on the other hand, there is no information about redness. The sun is so high that only the top of the rainbow is visible on top of the trees.

The lunar eclipse of the moon was visible in places

5.6. The half-shadow eclipse of the moon was successfully seen in places in southern Finland. There are small uncertainties in the appearance of the half-shadow itself, such as clouds, atmospheric transparency, and the Moon’s own differences in darkness. However, in some observations, the semi-shadow is likely to appear. (Photo by Ulla Vornanen)

Pollen rings of pine appeared in the sky

5.6. The pine has begun to bloom. This is indicated by pollen rings in the sky, which have been observed in southwestern Finland. In the perimeter of the pine there are typical brightenings in the low sun, as can be seen from the picture of Mikko Peussa above. Even further north, Ilmajoki and Kuusamo , a couple of recent observations have been made of weak pollen rings. In these, there is probably a weakly flowering birch this year, but the rarely seen spruce perimeter is also an opportunity.

The sickle of Venus stretched into a full ring

3.6. Venus has come closer to the Sun in the sky and at the same time its sickle has narrowed and lengthened. Several observers have photographed this development in the daytime with their telescopes. Yesterday, Rauno Päivinen received a sickle shot in Imatra. "The eight-year wait to get a decent picture of Venus's sickle stretching to 360 degrees was rewarded today," Päivinen writes. (Photo by Rauno Päivinen)

Observations from far away

31.5. The Sky Watch has received observations made by Finns from abroad in recent days. Above is the centaurus A , photographed by Tapio Lahtinen with a remote telescope in Namibia. With a Spanish telescope, he captures the comet PANSTARSS . In Reading, England, Reima Eresmaa , on the other hand, received a strong class of halo rarities for the film: the Kern arc and the 28 ° ring and the 28 ° lateral arc. (Photo by Tapio Lahtinen)

Mercury and Venus in the early summer sky

26.5. In recent days, observers have been targeting late-night Mercury and Venus. The light sky interferes with observations, especially further north, but Sari Pietikäinen managed to get a dimmer picture of Mercury from the height of Oulu. Even more challenging is Mercury found in the daylight using a telescope and an infrared filter, as Jerry Jantunen's observation shows, for example. (Photo by Markku Poutanen)

The night cloud season began

22./23.5. Summer is the time of night clouds and the first observations of this year were made last night in southern Finland . The clouds were typical beginners of the season, delicate and petty. The best night cloud screenings will be available in July and early August. Pentti Arpalahti was the first to alert and report to Taivaanvahti from the night cloud play. (Photo by Kari Saari)

The storm season is coming

18.5. Enthusiasts of extreme weather events have already got a small taste of the summer storm season in the form of hail, fine cloud formations and even a little thunder. The first findings focus on western and southern Finland . (Photo by Heidi Rikala)

8.5. The latest issue of Zenite presents the results for Haloh April. In addition, there are things about spring and late summer comets, Betelgeuse, the Moon, Venus and Mars. (Photo by Pirjo Koski)

The comet ATLAS is fragmented

18.4. Enthusiasts have followed the disintegration of comet C / 2019 Y4 (ATLAS). The first signs of the Sky Watch are already visible on 9.4. The brightness of the comet dropped to 9 magnitudes, where, however, it has remained for about 10 days. (Photo by Rauno Päivinen)

Venus and the Seulas met

3.-4.4. The planet Venus traveled across the constellation of the Seouls, or Pleiadians (M45). The event is repeated every eight years. (Photo by Timo Alanko)

Star enthusiasts follow the tail star from Atlas

25.3. About twenty reports have been made to the Sky Watch about the comet Atlas C / 2019 Y4 (ATLAS). The attached picture is from Jukka Laakso on March 21. A little tail has appeared on Atlas, as Harri Kiiskinen's observation demos . Pekka Parviainen's reports include several galaxy bypasses, such as 16.3. observation . (Photo by Jukka Laakso)

The Northern Lights play stretched from Utsjoki to Helsinki

March 20-21 at night, a Northern Fire was observed in almost the entire territory of Finland. As of this writing, only no reports have been received from the Lappeenranta-Lieksa line. The best prospects were experienced in northern and partly in the latitudes of Central Finland. Toivo Kiminki from Pudasjoki was the first to report the phenomenon to Taivaanvahti. (Photo by Voitto Pitkänen )

The battle in the north is advancing - zodiac light

19.3. Markku Ruonala has moved Taivaanvahti's northernmost observed track to the height of Kemijärvi. Around the equinox is the best time to detect zodiac light. Only a few days ago, Jani Päiväniemi took advantage of the window by piling Kuusamo Käylä as the northernmost place, where the phenomenon is at least visible. We look forward to what happens next. (Photo by Markku Ruonala)

This morning at SAR arc in Kyyjärvi

19.3. The special northern lights of the night sky continue. Antero Ohranen managed to photograph the Stable Red Northern Arc (SAR) in Kyyjärvi late in the morning. A strip of this tape stands out in the picture on the right. There are about a hundred observations of the SAR arc in the sky. (Photo by Antero Ohranen)

A rare Steve arch appeared in northern Finland

18.3. Tonight, a rare Steve arch was photographed in Pudasjärvi and Kuusamo. Jani Päiväniemi and Toivo Kiminki were the first to report on the phenomenon. If more observations come, the automatic link below will show them all. (Photo by Jani Päiväniemi)

This is what a two-second green flash looks like

17.3. In the morning, Petri Martikainen captured a rare green flash in Juva. The phenomenon appeared in the first detached fragments of the Sun's edge separated over the horizon for only about 2 seconds. At the very beginning of the attached animation, the green loose strips stand out in the second and third squares, respectively. (Photos by Petri Martikainen).

The zodiac light is now photographed at the height of Kuusamo

14.3. Jani Päiväniemi managed to record the zodiac light in Käylä, Kuusamo. This is, to say the least, the northernmost observation of the phenomenon. This may be a Finnish record. Zodiac light is a reflection of solar-plane orbital particles in the night sky. It is a spectacular destination at tropical latitudes, but only hard to spot at high latitudes. (Photo by Jani Päiväniemi)

The morning fireball appeared in the Oulu region

10.3. Kari Kaila was able to capture the fireball that occurred at 2.45 in the morning. A total of six observations were made, four from the Sky Guard and two from other meteor cameras from members of the fireball team. It was clear enough to see the phenomenon mainly in the direction of Oulu, (Photo by Kari Kaila)

Zenite 1/2020 appeared

27.2. The latest issue of Zeniit tells e.g. the depiction of the southern sky and the lunar eclipse in January. The magazine also provides tips for detecting zodiac light and lunar objects. Photo: Toni Veikkolainen.

The planet Venus shines in the spring evening sky

24.2. To the west, in the direction of the sunset, a bright spot of light shines from the early evening. It is not a star, but Venus, the planetary neighbor of our own solar system. The image also shows, as a dim light fog belt, zodiac light caused by sun-illuminated planetary orbital dust in space. Photo: Antti Taskinen

20.2. two bright fireballs flew over Finland

20.2. First, a bright fireball in the Finnish sky was seen at 3.35 in the morning and at 18.20 in the evening (see avaruus.fi). As of this writing, more than 30 observations have been received of the morning-night phenomenon and more than 180 observations of the evening's fireball. Ursa's fireball team investigating the cases hopes for more findings on the fireball form . The ball of the evening was also left in Tampere's Ursa meteor camera and Kyyröste's car camera .

A great halo play in Seinäjoki

4.2. the morning was in Seinäjoki during the handsome halo play of the whole sky. There were also numerous very rare halo forms. Erkki Tervola managed to immortalize all the splendor down to the halos in the opposite hemisphere of the Sun. If you have spotted halos in the last few days, you can submit your own observation using the halo form .

Solar enthusiasts gather at Tähtikallio

Ursa's solar system groups will meet on February 7-9. At the Tähtikallio Observatory in Artimärvi, Orimattila. A group of northern lights is also included. Performances include From Aurigo, Pluto and the Northern Lights. Welcome live or virtually. Photo: Janne Kari.

A new form of northern lights was found in the observations of the Sky Watcher

On October 7, 2015 , a strange Northern Lights phenomenon occurred, of which Mikko Peussa was the first to report to the watch . The phenomenon was repeated on October 7, 2018, when the University of Helsinki's Minna Palmroth group took up the mystery of Matti Helin's clue and first of all the observations of Helin, Pirjo Koski and Minna Glad . All of the dune plays in the study, published in AGU Advances , were on Sky Watch. More about the find: Avaruus.fi and Zeniitti . (Photo by Rami Valonen)

27.1.2020 A bright fireball in Lapland

27.1. An exceptionally spectacular and long-lasting fireball was seen above the Lapland sky just before four in the morning. The flight was missed by Panu Lahtinen's sky camera in Ivalo. If you saw an incident, record your own findings on the fireball form . Ursa's fireball team is investigating the case.

Lunar eclipse 10.1.

10.1. in the evening the half-shadow of the Moon was visible, causing the Moon to dim slightly from its lower edge. The eclipse was at its deepest at 9:10 p.m. Observations can be submitted using the blackout form . If the middle stage of the event is covered by clouds, you can select the title "Maximum eclipse behind the clouds". (Photo: 10 January 2020 Jaana Jalonen).
