Dim night shining clouds - 22.6.2022 at 01.00 - 22.6.2022 at 01.30 Helsinki Observation number 107307

Visibility II / V


There were some standard clouds in the sky, but not too much to block observation. There was a pretty group between west and northwest. There were individual groups of waves and belts between the north and the northeast. In Figure 6, I gave a large dose of usmi to expose the wave groups. I marked with a circle a spot that stood out with my eyes lighter than the background, I could not see the waves.
