Quiet aurora band - 30.8.2021 at 01.20 - 30.8.2021 at 02.20 Salla Observation number 100794

Visibility II / V


I went to the yard every now and then to see if anything could be seen there. The Bz values were very positive for the evening, but somewhere in between there was a short spike for the negative. Something small was visible in the high northern sky, there was a small dance and momentarily bright. Above the head some shapes, but remained dim.

In the morning it is already frosty and huge amounts of fog.
