Visibility III / V

Arja-Sisko Airila, Ursa (Etelä-Suomi)

Clearly visible illuminating night clouds in the northern sky from northwest to northeast, long belts and waves. The night clouds are so low that they are largely behind the forest at my observation site. Weather clear, calm, temperatures +19. There were so many mosquitoes in the bouquet that I had to come away.
