Active aurora band - 10.2.2022 at 20.45 - 10.2.2022 at 21.45 Saarijärvi Observation number 104476

Visibility III / V

Not visible

On the way home, I noticed a few northern lights at the Saarijärvi juice, which then grew a little. After parking in my backyard, to Saarijärvi, I watched a light show in the sky. It was a bit dim at first in several different shapes until a northern lights belt appeared. Appeared really bright, despite the bright moonlight and the glow of the street lights.
