Pearl clouds

28.1.2023 at 16.30 - 16.45 - Lieto (IV)
Matti Helin, Ursa (Länsi-Suomi)

It was a wonderful show at the entrance. Up to about 20 degrees like clear night clouds and here and there pinkish greenish single clouds. Unfortunately, only the lower clouds came rushing back and the whole show dried up.

Comet with naked eye coma ZTF

27.1.2023 at 00.15 - 01.30 - Lieto (I)
Matti Helin, Ursa (Länsi-Suomi)

The weather was pretty good, the ground was black and the sky was relatively foggy. The light pollution was a bit of a problem, but in the end the picture turned out to be ok. Image made of 20 images, each exposure time 8-10 seconds. The pines from the single photo are attached separately to the stack. Baking DS pictures is not a familiar task at all, so the adjustments were made with a so-called mutt.

Pearl clouds

26.1.2023 at 15.15 - 18.00 - Lieto (I)
Matti Helin, Ursa (Länsi-Suomi)

A beautiful display. There were also a few clouds of water ice pearls. A special phenomenon was a clear orange-brown glow opposite the sunset that was visible on land around 5:30 p.m. I have never seen such opposition before (photo 2) Several panoramic blanks were taken, but we'll see, because we can attack them. One hastily done included, but it has a little bit of everything... Last picture about an hour after sunset.

Binocular comet ZTF

20.1.2023 at 23.45 - 00.20 - Lieto (II)
Matti Helin, Ursa (Länsi-Suomi)

It was difficult to find, since there weren't really any bright stars in the area to navigate with. Finally found it. Seen quite well with 7x50 binoculars, clearly dimmer than for example M31, but quite close to M42... Maybe M31 and M33 in between. Greenish gray waste.

Binocular comet ZTF

16.1.2023 at 20.00 - 22.00 - Lieto (II)
Matti Helin, Ursa (Länsi-Suomi)

The weather forecast predicted that it would clear up, so there was a rush to try to catch comet C/2022 E3 (ZTF). The first attempt went to the magpies when the sky filled with clouds. Later in the evening it became clear and I found the comet low above the forest. Unfortunately, there was a lot of light pollution in the backyard, but something ended up on the cell. Image composed of nine eight-second exposures.

Uranuksen peitto

2.1.2023 at 00.20 - 00.40 - Lieto (III)
Matti Helin, Ursa (Länsi-Suomi)

For the first time I saw a cover of this song. The planet was rather faintly visible, but it was still easily visible when viewed through a telescope. I took pictures a few minutes before covering up. I enjoy the covering itself visually. Counting in my head, it took a little less than three seconds to cover. The covering itself was clearly visible. Uranus began to dim steadily and finally disappeared behind the disk of the moon. I couldn't wait any longer for the appearance, the countries of my dreams were calling. Photo taken with a cell phone through the eyepiece. Magnification used is ...

Light pillars

13.12.2022 at 17.00 - 17.20 - Lieto (II)
Matti Helin, Ursa (Länsi-Suomi)

Nice show, but fast. Unfortunately, I didn't have time to look for the tripod, so I had to make do with the hand photos.

Moon and Uranus

5.12.2022 at 17.15 - 17.30 - Lieto (II)
Matti Helin, Ursa (Länsi-Suomi)

The moon was supposed to cover Uranus on December 5. around 19:00. I took a few pictures after 5 in the evening, when a patch of clouds was already forming in the sky. Luckily I took it, because at the time of the eclipse the sky was completely covered. to the clouds. In the pictures, Uranus was faintly visible, but still clear. The blue color is striking in the pictures, it has not been emphasized at all. The triple image is from Stellarium, at 17:34.

6.11.2022 at 13.40 - 13.50 - Lieto (V)
Matti Helin, Ursa (Länsi-Suomi)

A rare light phenomenon, the November sun, appeared for a few moments. I took pictures of the cracks in the clouds and there was a speck there. The faculae were also very clearly visible.

At least 5 lightning strikes seen

16.10.2022 at 22.00 - 22.40 - Lieto (III)
Matti Helin, Ursa (Länsi-Suomi)

Jeez, what weather postponed it. The wind tears in the corners so much that you are almost afraid that the roof will fly off. A dozen or so seagulls were visible, and a couple of rumbles were heard.

Sun

Matti Helin, Ursa (Länsi-Suomi)

I was doing chores in the yard when I heard voices from high in the sky. A handsome flock of curlews circled overhead, gaining height. Soon the flock started to form furrows. who started to join towards the south. I ran to get the camera, just in case there were more cucumbers. At the same time, I thought that it would be fun to have the wretched with the sun in the same picture. Especially when the sun is embroidered by many dot groups, including AR3112. That is, according to the sun filter. Another flock flew over. And then the third. I followed one of the flocks and saw that the direction w...

Tertiary rainbow

30.8.2022 at 20.15 - 20.35 - Lieto (I)
Matti Helin, Ursa (Länsi-Suomi)

A really bright double arc in the eastern sky and steady rain all around set the higher order radar beeping. I closed the scope and shot from the sunny side. You couldn't see anything with the naked eye, but by handling the curves popped out nicely. Especially the fourth arc was surprisingly "bright".

At least 10 lightning strikes seen

28.8.2022 at 23.00 - 01.00 - Lieto (V)
Matti Helin, Ursa (Länsi-Suomi)

In the evening, it started to look like the thunder was seriously coming. I went to the edge of a nearby field and immediately in another picture, lightning (picture 2). Too bad I set the focal length a little too tight. Later, in the middle of the night, another thunderstorm came, but unfortunately with heavy rain. I had to photograph from under the canopy and the front area corresponds to it. Well, regardless, a great experience. The lightning that struck in the black night sky was almost blinding and a few flashes left small afterimages for a while.

Lightning photo

19.8.2022 at 15.30 - 16.10 - Lieto (III)
Matti Helin, Ursa (Länsi-Suomi)

Thunder rose from the sea. I followed the radar and estimated that a fairly good lump would rise somewhere between Lieto and Marttila. There then. Well, it did rise. But right in the area where I was standing, the front crashed. Good areas went by on both sides. I didn't dare go after them anymore, so I tried to save what could be saved. However, something was caught. And I got the flash with the still unthreshed grain field in the same picture. The air was really grinding.

At least 10 lightning strikes seen

19.8.2022 at 02.15 - 04.00 - Lieto (V)
Matti Helin, Ursa (Länsi-Suomi)

The forecast predicted a night thunderstorm in the Turku region. I set the alarm to wake up at two and collapsed into the blankets. When the clock chimed, I got up and looked outside for a moment. Flash. The rain radar also revealed that a thunderstorm front was approaching. I estimated that it runs along the coast of Turku in the direction of Pori, so I decided to drive to the rock of Vanhalinna, from where I assumed the lightning could be seen comfortably. And yes, the lightning was nice to see. Very comfortably. The distance to the thunder was about 15-50 kilometers. The air was hazy with h...

Bright night shining clouds

7.8.2022 at 23.30 - 02.00 - Lieto (IV)
Matti Helin, Ursa (Länsi-Suomi)

It thundered lazily in the Archipelago Sea. I was in pain when I came to the nearby rock in the evening. I looked towards the sea, where it flashed. I set the camera to shoot and the moment flashed again. Lightning flashed on the rear screen. Dim, though. The distance to the thundercloud was about 80 kilometers. The cloud quieted down and I waited to see if a new cell would rise. A message flashed into the phone: Northern lights. I wondered for a long time, I hadn't followed repo activity at all. I gazed northward for a quarter of an hour, until a bunch of dim, greenish rays rose next to a...

The day in Särkänniemi had a great ending when a wonderful double rainbow lit up on the way home.

Arcus cloud

9.7.2022 at 14.00 - 20.30 - Lieto (I)
Matti Helin, Ursa (Länsi-Suomi)

It was the kind of day to cut off the branches and cut off the top. For the rest of the week, the forecast was that the Turku region, among other things, would experience thunderstorms on Saturday. And so it happened. After two, I saw the first flashes, right from my backyard. There was a rush. But where are the camera batteries and shutter release? Nowhere. In pain, I wandered around the house, I dug through the back boxes of cars and other things. Can not find. I was already leaving for work to check if they had stayed there. Well, in the end the stuff was found under the cushion of the armc...

Clearly visible night shining clouds

8.7.2022 at 00.20 - 02.40 - Lieto (III)
Matti Helin, Ursa (Länsi-Suomi)

A show disturbed by low clouds, which I don't think was anything too amazing. The sky is still pale. In the east, there was a really nice belt and wave area. So, I spent the hours of the night photographing the spider web. And I solved an ancient mystery: What do night clouds look like through an infrared filter? Answer: Not at all.
