A night of starflight and northern lights

December 14-15 With the exception of Eastern Finland and northernmost Lapland, which are covered with clouds, a great northern lights show was experienced. That night was the maximum of a gang of starbursts. Moving to the midnight side, the radiation point of the meteor flock rose to an ideal high and geminides were abundant.

A binocular comet hurts north

The binocular comet C / 2013 US10 (Catalina), which previously moved in the southern hemisphere, is finally visible in Finland . Primarily, pictorial observations are requested from the comet. Photographic observations will also be accepted if they are accompanied by an adequate observation report. Photo: Tapio Lahtinen

Twilight ball

2.11. A bright fireball was seen over southern Finland in the twilight sky around 5:40 p.m. Observations on the case are collected on a fireball form .

Mon / Tue night possibility for northern lights

1.11. On the night between Monday and Tuesday 3 / 4.11. there is a good opportunity for northern lights also in southern Finland. Forecasts are always uncertain and no weather can be promised, but in the evening it is worth monitoring the situation. Northern lights observations can be reported using the northern lights form .

The evening fireball dropped pebbles into the sea

26.10. At about 5:40 pm, a bright fireball was seen over southern Finland. The piece could drop a meteorite into the Gulf of Finland. The fireball was also recorded in the image of Panu Lahtinen's sky camera in Espoo. Observations on the case are still being collected using the fireball form .

Venus, Jupiter and Mars shine in the morning sky

24.10. morning naps have been delighted by the encounter of the three planets at sunrise. Jupiter, Venus and Mars appear side by side in the sky. In addition to the mentioned planets, Mercury is also visible in the morning sky and the Moon has visited the planets in its orbit. Pictorial observations of the autumn encounters are collected using the Solar System form.

A big explosive fireball in the direction of Sweden

In Sweden 23.10. a large fireball seen in 1958 was also observed from the west coast of Finland. About 30 reports of the incident have arrived at the Sky Watch. The phenomenon was also observed in Norway and Denmark. The estimated fall area is off the coast of Sweden, a few tens of kilometers from Stockholm.

Bright fireballs

Rare halos in the daytime sky

In the afternoon 9.9. rare halos (eg Wegener's arc, blue line, 120-degree side sun, Parry's arc) were observed, especially in southern and central Finland. More common halos were observed throughout the day, but the peaks peaked at most observation sites for only a short time. Photo: Matias Takala .

The northern lights play illuminated the night

7 / 8.9. northern lights were seen throughout the country. Although the cloud curtain hindered observation in some places, the northern lights were admired during the night all the way to Helsinki and Denmark.

In southern Finland, the fireball was covered in clouds. Those who have seen the fireball are asked to record the observation on the fireball form . (photo: Markus Kiili )

A great northern lights play that brightens up from time to time

28.8.-29.8. as far as the south coast, a northern lights play was visible. In the southernmost part of Finland, the play was dim for most of the time, but sometimes there was a sub-storm with active belts and very bright northern lights in color with the naked eye.

Northern lights and illuminating night clouds

15 / 16.8. there was an admirable rare show: in the summer night sky appeared both green northern lights and illuminating night clouds at the same time. Clear weather favored observing the sky without lapping northern Lapland, and more than 100 observations have arrived at the Sky Watch at night (photo: Mikko Lönnberg).

Observations are collected from the maximum of the perseids

The maximum of the Perseid meteor flock was 12./13.8. Data on the activity of the flock are collected using a solar system form (target ' Meteor Flock '). The observation can be accompanied by a picture of a meteor belonging to the flock or a report on the number of star flights during a certain period of time (photo: Janne Alatalo).

Aldebaran was covered behind the moon

9.8. The declining crescent moon covered Aldebaran from about 1.30 to 2.20 p.m. Observations of both obscuration and occurrence were obtained in the Sky Watch (photo: Kylli Pöyhönen).

The best of the night cloud summer

For two consecutive nights 22./23. and 23./24.7. saw the best night cloud plays of the summer so far. In both, the night clouds hurt in places remarkably strikingly bright. However, the latter play was more extensive and diverse (photo: Peter von Bagh).

Bright pyramid halls in southern Finland

25.7. In the afternoon at about 4 pm, a rare and bright halo play created by pyramidal crystals was seen in southern Finland (photo: Olli Hintikka). The best play was seen in the Helsinki metropolitan area and the surrounding municipalities, although observations of the Sky Guard came from elsewhere as well.

Venus and Jupiter met

The encounter of the two brightest planets has been closely monitored in both the evening and daytime skies. However, the best shots were obtained from the southernmost latitudes. The picture below was taken by Ari Ollikainen in Platanias, Crete.

Night cloud season opened

Finland's first night cloud observations this summer have been made. The season was opened by Juuso Nurmio in Turku (see photo). Night clouds were visible elsewhere in the southwestern parts of the country, but to the east detection was hampered by other cloudiness and, to the north, the brightness of the sky. The Rare Cloud Types form can be used to report night clouds.

A new version of the Sky Watch Android client

19.5. A new version of the observation browsing application developed by Arto Oksanen has been published. In the new version, the improvements focus specifically on image browsing features. The app is free to download for devices running the Android operating system.

Spectacular fireball

3.5. Around 11 pm, an exceptionally handsome fireball was seen in Central Finland. The fireball was also recorded in Mikkeli's Ursa sky camera (Photo by Aki Taavitsainen). Observations of the phenomenon are desired with a fireball form . The route of the fireball has been modeled.

Vesa Vauhkonen has the world's newest halo discovery

About a year ago, Vesa Vauhkonen's observation has found the world's first photographs of a halo shape theoretically predicted 168 years ago. The arch described by Vauhkonen is a continuation of the successful work of Finns in recent decades in documenting new halo phenomena.

Haloh April begins

With the arrival of spring, the bright time increases and the conditions for the occurrence of various halo phenomena are often good. This year, too, a special observation campaign called Halohu April will be held in April. Both pictorial and non-pictorial observations are collected on a halo form .

Service outage on Thursday 12.2.

Thursday 12.2. The Taivaanvahti service has a maintenance break of a few hours. Minor changes are being made to the system. As a new feature, e.g. much-needed multi-observer support for observation forms.

The comet Lovejoy is still visible

10.2. Comet C / 2014 Q2 (Lovejoy) is still a binocular target in the evening sky . Tapio Lahtinen and Toni Veikkolainen made the first observations of the comet Taivaanvahti at the end of December.
