Quiet aurora band - 30.8.2021 at 01.00 - 30.8.2021 at 03.30 Valtimo Observation number 100798

Visibility II / V


The night provided a decent storm with moderately modest solar wind characteristics. Most of the time there was only a dim pink / green arc in the sky, mostly camera-separable, but after the storm started for a few minutes, the play was beautiful. Cloudiness interfered with filming. At times the green oxygen emission was even moderately bright, but as a whole I marked this as a dim play.
