Visibility II / V
After ten o'clock in Nurmijärvi there was a Z-dip and before 11 pm something started to separate from the pictures and then the performance just went on and on. All the while, the sky was delicately green by tens of degrees. Based on the Tampere camera, real estate agents could trade northern balconies with excellent northern lights. Before one after midnight, the flashes of the rays separated my eyes as well. There also seem to be some reddish spots.
Edit. Images require intense processing. There are unnecessary extra sources of interference light outside the field of view. The red spots and the radiant line on the left may be some reflections, but there are real repos in the pictures.
