One halo form

Almost complete, relatively. tepid 22r tire.

Diffuse glow

Georg Kieninger

I happened to look at the interference curves at night and immediately set the camera to continuous shooting for 3 hours. The northern lights were perhaps not very strong, but the gauzy, sometimes the rays, remained there the whole time and also moved. The best stages were between two and five o'clock. The attached timelapse is a compilation of approx. 180 frames, i.e. the aurora borealis was recorded in every single image. The purple color is also visible in the pictures taken shortly before 5 o'clock.

Half-sky auroras

18.9.2023 at 21.30 - 04.00 - Helsinki (IV)
Georg Kieninger

By far the best northern lights show this fall. The finest continuous phase lasted until about midnight, after that sometimes nothing was visible, sometimes a little more. Even at 4 o'clock, something green could be seen.

Quiet aurora arc

14.9.2023 at 21.52 - 23.55 - Helsinki (I)
Georg Kieninger

Even though the curlers did not allow us to expect anything miraculous, a variably bright arc lingered over the center for a couple of hours, even rays were visible momentarily (picture 2). It was once again confirmed that the measurement values describing the magnetic activity are only indicative; about a week ago - was it the 3rd and 4th of September? the night between - based on these values, one could have expected an actual aurora borealis spectacle, even more so when there were excellent, i.e. clear, weather conditions throughout the night. But nothing was visible. But that's okay, o...

Quiet aurora arc

An arc and some rays too. I think I missed the best stage every start at three o'clock. However - the opening of the repos season! It's good to move on from here.

Perseids

I saw those Perseids in the center of Helsinki too, the conditions were the best.

Clearly visible night shining clouds

20.6.2023 at 01.15 - 01.45 - Helsinki (III)
Georg Kieninger

I happened to glance to see if there were any night clouds. And there they were in a wide area from east to southwest and very high up, although not quite up to the zenith. I didn't follow for a longer time, so I can't say anything about the time duration of the (delightful) phenomenon. I think very dim night clouds were visible in the west as well, but I didn't take pictures of them. I added a third, i.e. a panoramic image consisting of five frames, which stretches from east to southwest, in order to get a better idea of the scope of the phenomenon.

Diffuse glow

23.4.2023 at 23.00 - 02.40 - Helsinki (I)
Georg Kieninger

The curls promised really wild aurora borealis. After it got dark, I started to follow them and I was a little disappointed at the beginning, because the thin thin layer of clouds in the northern direction prevented proper visibility. After all, something was visible (picture 1). After midnight, however, the situation changed decisively, as the aurora borealis began to be clearly visible to the eye at the very zenith and almost to the south (picture 3, it is photographed facing east-southeast and shows Suomenlinna church tower on the left and Harmaja pilot station with lighthouses on the right...

Satellite

22.4.2023 at 23.34 - 03.01 - Helsinki (III)
Georg Kieninger

I set the camera to record the series because it was the maximum of the lyrid swarm. And quite a lot caught the cell, mostly satellites. I will put two pictures according to my observation: picture 1 is a compilation of approx. 60 satellite frames. The picture is not very high-quality because I only added streaks caused by satellites to one still picture. That's why it has so many small millimeter-long cross lines. If I had stacked these images as they are, it would only show semicircle-shaped streaks of stars. I didn't even try to find out the names of the satellites when there were s...

Weaving in front of Helsinki again

Mirage

21.4.2023 at 14.30 - 14.55 - Helsinki (III)
Georg Kieninger

Weaving on Helsinki's sea horizon. Figure 3 is interesting in that the three objects shown in it are not ships, because on at least two other days they were seen again in exactly the same places. Could it be, for example, reflections from the structures of Vuosaari harbor, e.g. cranes?
