For a long time in the south, too, a decent show, although the active phase lasted less than 10 min. Before that, however, three arches were visible, the top of which was really dim. Longer timelapse video:

Timo Oksanen

I was outdoors filming the Northern Lights at 6:30 pm to 9 pm and 10:20 pm to 11:30 pm. The camera stood out well in places, with the eyes very dim. Apparently, the most active stage was just as I was walking inside - just before ten, peeking through the front door, I could see a very clear dance in the sky. Evening service with timelapse video:

On the way north in a 39-degree fever (I didn’t drive myself!) And a 30-degree frost, however, I had to stop when something like this happened in the sky.
