Clearly visible night shining clouds - 28.7.2021 at 00.15 - 28.7.2021 at 00.45 Mäntsälä, Ohkola Observation number 100022

Visibility III / V

Teppo Laitinen, Keski-Uudenmaan Altair

I was in a regular place listening to the sounds of forest animals at night and at the same time admiring the night clouds visible to the north. This time they were low and at times the lower clouds obscured the view, but as always they looked great.
