Visibility IV / V
Here is the surface solar arch that finally came to Rovaniemi on February 8. Although it had been cold and windy for several days, the seams had always gone so far that at least light frosty snow had come at some point at night. But the night before Day 8 was snowless and clear.

The maximum stacks are quite interesting. They reveal how bright glints, which I considered random glints, are not random at all, but are missing from the surface of the surface solar arc. And even between the forks of the surface solar arc is this glint, less intense. Something colored stitches can be seen there as well, the random glints on the left side are greenish. Maybe they would be right if that side was just as bright, know him. On the right you can actually see a pink glint (even a little on the left). Thin film interference? Or just shake your hand and say it’s just “just something” now, maybe the stacking method of Artea or Samujampa’s bad optics.
That's how the pictures are stacked on Lahtinen's excellent Halostack. Although it prolongs the stacking time, I still used a command that aligns the horizons of the images with each other. I couldn't get that solar arc to spread unnecessarily. Admittedly, even if not put in line, the result would still be perfectly valid. According to Halostack, the tilt of the images was at most only of the order of 1.5 degrees from the reference image. So you can get these flakes by hand at a fast pace.
