Half-sky auroras, Ulvila

An experiment to get a corona discharge on video recording with the south-west camera of Karhukamera (Karhu VI). The camera could not be turned closer to the zenith, but at least something was captured from this.

EDIT: addition to observation (March 17, 2023):

The Northern Camera recording before and after the rapid appearance of the corona eruption (around 01:00) is worth watching via YouTube. Too big a video to share here, but the video shows a lot of these repos as well!

Especially the pulsation of the northern lights is better visible, because the individual images have a very short exposure time, 15 frames per second, and current surveillance cameras are surprisingly sensitive and accurate in terms of their dynamics for observing the northern lights.

Of course, the video has been sped up 32 times, because otherwise its duration would be unbearably long for many people (two hours of recording). It's worth a look, because you can see these "pulsating aurora borealis" quite well - and much more...
