I try to follow also this event, in central Finland, if conditions are ok. Current estimate is partially cloudy sky and temperature around -23...-25C.

fyi, Set of surface halos, the rare type visible here. It is two diffuse lines on both side of sun. I do not know the correct name of halo in english, in finnish it is referred as "Pinta-aurinkokaaret [Luomanen]" or "Luomasen kaaret". More info (in finnish) and simulation images, can be found by cli...

I use UFO capture v2 on my two meteor cameras.... other comments from UFO capture, before considering purchase video settings... PAL/NTSC settings in my setup (UFO capture v2) cannot stay in user defined values. Basicly I select suitable 720*576 resolution and PAL_B mode. After PC is booted, UFO ca...

I use UFO capture v2 on my two meteor cameras (Watec 910HX), both running on same PC. I have selected a "path" of multiple lower resolution cameras, instead of high res & fisheye lens combination. To my understanding, Sonotaco does not anymore update UFO Capture v2 (although these was an option to b...

I still have a Tokina 12-24/f4. Used it mainly with old Nikon ... I do not like that lens. Even if the lens is correctly focused, the corners look quite a bad and blurred (also at f8 or f11). I guess there could be optical or mechanical problem in my lens. Have not heard that all the Tokina 12-24/f4...

Any ideas why the rings are not round, most clearly this is visible at first and second images ?

fyi,

one photo at Borlänge from opposite side of sun, by Natalie Åkerstöm.
https://www.taivaanvahti.fi/observations/show/79795

I am not sure about that image, from google (it looks like a stitched panorama, so precise analysis based on panorama may not be accurate). At least these seem to be additional images at SVT web site: https://www.svt.se/nyheter/lokalt/dalarna/se-ljusfenomenet-i-borlange also on YouTube: https://www....

I also noticed the "Heja Sverige" comment It is also worth to mention, that in the unsharp masked image, there is a second arc visible on top of CZA.

Interested to hear, did you see any auroras...?
