Eye-catching night shining clouds - 21.7.2021 at 00.16 - 21.7.2021 at 02.05 Espoo Observation number 99819

Visibility V / V

Mika Yrjölä, Ursa (Etelä-Suomi)

The already traditional beginning of this summer’s observation of night clouds started with clear and visible night clouds seen from the balcony from the holiday of the trees. When I got out with the shooting verms, there was an immediate feeling that there was now an unusually handsome set on offer; at this point the night clouds were visible for more than half the sky and were handsome.

Already by the seashore I had to take a few pictures and the next almost two hours went by taking pictures of night clouds with water, buildings and trees on or near the Kivenlahti shoreline. The 152-image timelapse also accumulated, though unfortunately due to the slightly misplaced camera settings, two short pauses appeared, which appear as jerks. This time, the mosquitoes didn’t torment me either, so whatever it was while enjoying the views. Two more countries went home a little annoyed when they had to leave the show in the middle because of the work day ahead.

The observation site does not cover all the images, but is where most of the images are, but the rest are within a radius of about half a mile.
