Jupiter

2.10.2022 at 01.08 - Lappeenranta (III)
Jerry Jantunen, Ursa (Helsinki)

I was waiting for a possible gap in the clouds, and Jupiter finally hit a suitable gap for one short video clip. Europa and Ganymede were visible next to Jupiter. Collimation wouldn't have been bad, but there wasn't enough cloud gap for that.

Rare halos

3.10.2022 at 12.25 - 12.35 - Tampere (IV)
Johannes Dahlström

Stumbled upon while walking around in the center of Tampere. In addition to the usual 22° stuff, there was more to be found in the sky when I stayed for a while to look. The contrast and clarity of the images have been increased, which brought Parry quite clearly into view. I can't vouch for the identity of the 46° halo, but apparently ysk is more likely than a ring?

Several halo forms

3.10.2022 at 07.49 - 08.50 - Turku (II)
Paula Mattila

A bright 22ys started the halo day, by nine also came 22r, side suns and solar pillar. When after ten there was another chance to observe the sky, you could still see the side suns otherwise the sky was covered by lower clouds.

Milky way

1.10.2022 at 20.56 - 01.16 - Naantali (III)
Lasse Nurminen

The Milky Way stands out fairly comfortably in the direction of Merimasku, although the distance to the light pollution of the Turku area is not impossibly long. Of course, the shooting direction is away from the glow of the interference light, so that also helps in capturing the subject better. Occasional clouds hindered the view from time to time. The first picture from nine corners and the latter from the end of the observation time.

One halo form

2.10.2022 at 17.52 - Naantali (I)
Lasse Nurminen

Dimly gazing throughout the day starting in the morning whenever the lower clouds retreated, in the form of side sun, zyk and 22° ring. Along with the perches, there was less of a photo opportunity, but the evening sun on the left side was bright enough that I had to capture it. Of course, at that point we had already reached the shore and a longer camera was also available.

IC 1805

5.9.2022 at 22.00 - 23.59 - Hyvinkää (IV)
Antti-Jussi Pyykkönen, Ursa (Etelä-Suomi)

I tried shooting a classic subject at a short focal length with a little APO, which I've kept on the shelf for far too long with other projects. For this picture, I also practiced JP Metsävainio's tone mapping technique and now I realized in practice what a wonderful process it is.

Quiet aurora arc

1.10.2022 at 22.25 - 00.55 - Mäntyharju (II)
Antti Taskinen, Joensuun Seulaset

The aurora borealis in the sky of Mäntyharju remained silent. With the naked eye, you could only see a very weak reflection low in the north, the camera did capture shades of green and red. Weak aurora borealis are good for taking a star streak photo.

Object K

26.9.2022 at 21.39 - Kokkola (III)
Pentti Ketola, Ursa (Länsi-Suomi)

I photographed the following phenomenon in Kokkola on the evening of September 26, 2022 at 23:24, which I don't think is a satellite. The pictures have been reduced from the original and the other one has also been cropped.

Active aurora band

27.9.2022 at 21.39 - 22.20 - North Pole (III)
Timo Nyberg, Ursa (Helsinki)

Photographed from the cockpit of Finnair's Tokyo-Helsinki flight (AY 74) just after crossing the North Pole. In some of the pictures Jupiter is bright, in some the Taurus constellation with the Pleiades constellation and the planet Mars. After crossing the North Pole, it got dark very quickly (times are UTC times) and almost at the same time the northern lights came into view. The main color was of course green, but there were also reddish and blue colors. Very bright and active aurora borealis, after all we pilots had been given a warning about strong space radiation. Photo taken with iPh...
