Visibility III / V
There is a fireball camera observation.
And in fact, my first observation is with an infrared fireball camera. (The camera is infrared to make any daylight bulbs better visible in a much darker infrared sky.) At least now, northern lights are visible in light pollution with good contrast.
It started at about 20 degrees and pretty quickly dropped to a lower angle. Apparently, with a quick look at the window, I saw one of them already at a clearly lower elevation angle than the beginning.
Of the images, the one chosen as the main image was in fact second in time, the other two in the correct chronological order.
EDIT: I corrected the time when I quickly copied UT time from the image names to it. Anyway, it must have been the end time, now the start time.
