Rare halos

2.9.2021 at 09.18 - 16.14 - Kouvola (III)
Tero Sipinen, Ursa (Etelä-Suomi)

I noticed a modest piece of tire in the morning sky. I optimistically left the camera on duty when there was such a nice looking cloud. I remembered to pick up the camera in the living room in about an hour and a half. Even then, nothing was really visible, and the timelapsen was not recorded except for the halo fads (Fig. 1, 9.18–10.55). In the afternoon, Petri Martikainen made a whirlwind . A glance from the window showed only a short section of diffuse ring behind the lower clouds so there was no way to rush out. However, after finishing the work, I went out with the camera. As a nice surpr...

Quiet aurora arc

Atte Ahola

I went to work in the evening as soon as I got to Loukkumäki in Karkkila. I had followed the metrics and other observations / interpretations in the Facebook Northern Lights Firefighters group throughout the day. So with a hopeful mind on the move. After climbing the hill, I was looking for the northern direction of the air and started shooting there and adjusting the camera. There was a dim arc that could not be distinguished by the eyes. Then a little radiation began to appear under the eyes. I hadn’t gotten to photograph the northern lights before so this time I went completely practicing a...

Reflected primary rainbow

Ari Koivisto

Hey! On September 18, 2021, at 6 p.m., when I came home, I noticed from the front door, looking behind the clouds at the edge of the forest, clear adjacent beginnings of the rainbow heading in opposite directions. While there weren’t actually wider rainbows, I took pictures with my handheld camera so I wouldn’t have time to go away. I was annoyed afterwards that I wasn’t looking for a better camera inside. Fortunately, the phenomenon was visible while I was photographing it and still remained visible when I left. I remembered the phenomenon on 23.9. and google it for more information. I came a...

Glory on air

23.9.2021 at 05.15 - 05.45 - Juva (III)
Petri Martikainen, Ursa (Itä-Suomi)

I woke up at five in the morning and went hunting with a drone on the Moon. The attempt of the previous morning had crashed to the rocks right from the start, when the drone refused to ascend, but demanded that the compass be calibrated. Well, I couldn't do it in the dark without a manual. Fortunately, the trouble later recovered on its own. This time there were no problems with the drone, but the dilemma was to find a decent fog. I set off to drive to the destination I was thinking about in advance. Already a couple of miles away was the first fog ferry over the road. I stopped at it and ...

There is really nothing to say about the phenomenon, that special. Looks like a stationary flash

Quiet aurora arc

21.9.2021 at 23.00 - 02.00 - Tampere (II)
Kari A. Kuure, Tampereen Ursa

We see the northern lights in the sky lit by the full moon. As the cloud cover receded, the north camera on the observatory recorded a dim arc of northern lights and occasionally associated rays. The bright moonlight brightened the background sky so the contrast remained low. Times are UTC times.

Aurora rays

22.9.2021 at 03.14 - 03.21 - Helsinki (II)
Pentti Arpalahti

Timing is essential. When the Tampere camera had a nice-looking belt and the window showed greenery after one, I went through three outdoor observation sites in less than an hour and a half - after going through> 40 images in a few images, an uncertain belt that wasn't enough to exceed the reporting threshold. At the end of the toil, a glance at the celestial cameras and out of the window -> For seven minutes, a vibrant belt appeared and beautiful splashes of rays that were clearly visible to the naked eye!

This is a rather exotic Messier site considering Finnish conditions, as this fog is visible at very low latitudes in Finland. In this image, the object is at a maximum height of about 2.5 degrees above the horizon.
