Dim night shining clouds

24.8.2021 at 03.00 - 04.10 - Oulu (II)
Thomas Kast

I had to drive home after looking for the northern lights and noticed that there are illuminating night clouds in the sky. Had to take pictures until it was too bright.

Quiet aurora arc

24.8.2021 at 00.52 - 01.45 - Oulu (II)
Thomas Kast

It was finally a good weather and at first there were a few illuminating night clouds, then a little before one started to have a very weak arc, had to check with the camera whether there was fog or northern lights. Oh this happiness while it is dark enough! On a few occasions it became more intense moments and then it evaporated. At three o'clock I was driving home when I noticed that the illuminating night clouds were getting stronger and rising. I still had to go photograph them when it was too bright. The dream tasted good after this :)

Quiet aurora band

Thomas Kast

Last night's northern lights were calmer than a couple of nights earlier but just as beautiful to watch. The Bay of Bothnia is beginning to melt and in places water was already found for reflections. A relaxed night at zero and Lady Aurora dancing in the moonlight.

Half-sky auroras

3.2.2021 at 21.10 - 00.30 - Muonio (IV)
Thomas Kast

Northern lights started well in advance yesterday, but then came the clouds. I drove to Muonio hoping to find a clear sky. I always stopped and checked the situation from time to time. It didn’t look good for a long time, but then I came to this place and the stars appeared among the clouds. Then came the rush as the reposet seemed to intensify suddenly. When I took this picture it was almost a day, the northern lights really bright for a moment. After that I continued to different places and you will be seen for a really long time everywhere in the sky, even a benign strong corona for a long ...

Quiet aurora arc

26.8.2020 at 00.40 - 01.50 - Oulu (II)
Thomas Kast

I went last night looking for northern lights and noticed lightning over the sea. The Northern Lights also showed up somewhat and this created a very top combination of what I have been waiting for for a long time.

Thomas Kast

I went to the lake at night when it looked like there might be northern lights at some point and shortly before 1.30 it started to show when it was dark enough. After that, there was a great moving show in the sky and on the water for a few minutes. Comfortably there were illuminated night clouds on the left and Venus on the right.

Pearl clouds

31.12.2019 at 11.30 - 15.15 - Enontekiö (V)
Thomas Kast

I went driving south from Kilpisjärvi to look for the clear sky and the colors of camouflage. I would never have thought I could see pearl clouds and still see such intense colors. I shot for over 3 hours in all sorts of shapes, close to and with the landscape. In the beginning the colors were subtle and as the sun went down more, there became really intense colors, especially orange and purple. A memorable experience of what makes the heart continue to round.

Image of an exceptional thunder cloud

17.6.2019 at 20.40 - 21.00 - Ylitornio (V)
Thomas Kast

I saw a black cloud breast as I drove north at Ylitornio. As I drove closer, bright flashes appear but not yet in cloud form. In the village then I noticed this ‘rinkula’ or donut. It was so special that I decided to stop even though it felt wrong when there was a thunder from all over. In the north there was heavy rain which can be seen on the right side of the picture. The sun was still shining in the south. Many hundreds of birds flew in the sky and were in some distress. In the picture, they are shown in the upper left corner. The cloud was just awesome and I’ve never seen anything like th...

Total lunar eclipse

21.1.2019 at 06.40 - 07.30 - Oulu (IV)
Thomas Kast

The complete lunar eclipse on January 21, 2019 was a challenging task. Even if I could look at the backyard I wanted to fulfill a picture dream that has long been on my mind. Unfortunately, it and also a couple of contingency plans crashed due to the circumstance. Luckily, I found that branch in the fourth place in the tree. Shooting 105mm at 7.15

Aurora rays

22.9.2018 at 20.50 - 02.20 - Oulu (II)
Thomas Kast

There were three big northern lights screens last night. The first one around 9pm passed when I looked at it from the car. This picture is from another show which was around 22.08. The third show brought a faint crown over his head, the moonlight slightly disturbing him then. I haven’t had time to go through the other pictures yet. High night!

Several bright halo forms

31.10.2017 at 22.15 - 23.45 - Enontekiö (III)
Thomas Kast

Last night, the northern lights hunt became a halo hunt. The cold weather (-22C) apparently got the ice crystals moving. I set off to drive from Heta into the darkness and first saw the familiar 22-ring through the fog. The 46-ring was really poorly visible and at the top was partly the arc of the zenith environment. I continued looking for a clear sky and it also came against me. It had a very different combination of moonshine. If I realize right, it shows the side moons, a 22 ° overhanging arc, and a partial horizon ring.

All-sky aurora

7.9.2017 at 22.40 - 04.40 - Enontekiö (V)
Thomas Kast

7.9. in the evening I went out at ten to look for a suitable place to shoot. At first, the arches were visible in the sky, moderate and sometimes fast. Two were supposed to be in the cabin but one stop and watching the data changed everything - thankfully. Pretty much the two immediately started a crazy show, became the crown of the crown after a break. Great arches, needles and in every direction. At first, green was the strongest color but for a while, purple was the main color and was able to stand out easily with the eyes (which is usually not the case). It was a completely incomprehensibl...

Active aurora band

18.8.2017 at 01.15 - 01.45 - Yli-Ii (III)
Thomas Kast

The opening of the Northern Lights season was about the same time as in previous years. The intensity was very different. The corona opening in the sun brought very bright northern lights even though we had to wait quite a long time at night. About a quarter over one began to perceive a very faint arch but suddenly it became clear. As the arch rose the northern lights radiated in the arc and the lights danced in the sky quickly. The play lasted just over 20 minutes and after that the sky was empty again.

All-sky aurora

14.12.2015 at 19.50 - 23.50 - Oulu, Oulunsalo (V)
Thomas Kast

Immediately in the early evening (around 6pm) the northern lights were visible from home. I packed the cranks and was at the scene around 7:50 p.m. There were already northern lights visible everywhere. Twenty minutes after that came a strong ‘wave’ with a crown where red was also visible in the eyes. At 9pm started to fade and I changed seats. After that, there was no more belt and ‘green mist’ in the sky. I drove home at 11.30pm and stopped once more when I just came back rel. strong belt. Sweet evening after such a long cloud break :)

All-sky aurora

7.10.2015 at 20.30 - 02.30 - Oulu, Haukipudas (V)
Thomas Kast

Quite as soon as it was dark enough the warps appeared in the sky. Getting out of the stray lights, he only realized how magnificent the northern lights in the sky warped. Very bright arches went through the sky, a little to the south. At the beginning of the night there was not much activity to the north. Later appeared everywhere and a few Korona landed. At ten o'clock there were strong northern lights in the north. Moved really fast and the clear red / pink was below the green as shown in one picture. Sorry for the typos.

The brightest moment of last night, shortly after midnight. The calm arc was in the sky for many hours. In between brighter and at the moment pretty fast moving.

The calm northern lights belt changed very fast for moving repos. The pillow weather provided almost perfect reflections on the lake surface. I put another picture showing four pictures taken in one minute. All part of a timelapse snippet. Good night!

Half-sky auroras

12.9.2014 at 23.50 - Oulu, Yli-Ii (IV)
Thomas Kast

The solar storm that brought the x-flare from the sun kept its promise and I got to watch a great show that started as soon as it was dark enough around 9.45pm. Then there was a break and shortly after 23.30 there were great northern lights and crowns for less than 45 minutes. After that, dimmer northern lights. The picture shows how the Corona rises from the horizon and the moment after that it was up.
