The magnificent aurora borealis all over the sky started as soon as the sky got dark. For a long time, the green cloud covered almost the entire sky and most seemed to be happening directly overhead. Several cameras shot timelapse in different directions, there was also something to shoot in the south direction. Figure 1. "Aurora borealis bubble" facing south at 22:56-00:29. Figure 2.

Half-sky auroras

CME again offered quite a spectacle. The cloudiness posed freezing challenges and it was up to the smallest detail so that the whole spectacle would not have been seen. The northern lights were currently spreading across almost the entire sky, offering in addition to green, red and pink hues visible to the eyes. One special feature was the so-called auroral streamer, which on the north side of the oval provided an arc-like stringy area like a substorm. Blue was also visible with the naked eye for a while in this area. In the bottom picture, these blue-toned threads. After the substorm, the sky...

I photographed the northern lights in Rusko and Turku. At the same time, my old camera filmed a series by itself on the balcony at home. I put together such a quick (approx. 6 seconds) gif animation from those pictures from 23:00 to 23:30 at the end.
