Clearly visible night shining clouds - 30.6.2021 at 00.25 - 30.6.2021 at 00.59 Espoo Observation number 99252

Visibility III / V

Mika Yrjölä, Ursa (Etelä-Suomi)

While visiting the balcony at midnight, I noticed a hint of illuminating night clouds, and while the summer vacation isn’t yet topical for its own part, I decided to go and describe a bit.

Outside, it soon became clear that this time the show was a bit unfavorable for these corners as the night clouds were mostly east / southeast and very close to the place where they would not be left behind much of the trees or houses. But I didn’t let it bother me, after all, it was nice to go outside for a summer night and cool off in the heat readings to counterbalance the interior of the still hanging home.
