Quiet aurora band - 19.10.2021 at 20.44 - 19.10.2021 at 22.15 Taipalsaari Observation number 101909

Visibility II / V

Repos almost lit by the full moon and partially covered by the upper clouds. The shift of the diffuse arcs past fine, at best 4 or 5 arcs were visible simultaneously in the sky. The substorm was milder than the beginning allowed. On the other hand, the images at the beginning are accurate but when I shot it I managed to sharpen the focus, so the pictures taken during and after the sub-poison are inaccurate, so .. maybe a little less annoying than if there had been a bigger sub-storm.

The first picture was taken at 20.44, the second at 20.49 and the third at 20.51. Fourth and Fifth at 9:16 p.m.
