Bright night shining clouds - 12.7.2021 at 23.45 - 13.7.2021 at 01.00 Espoo Observation number 99504

Visibility IV / V

I returned from the cottage from Kajaani to Espoo, here in the south it will be a dark and immediately comfortable night cloud bush. I periodically visit a nearby park to take a couple of raps in memory. Watch the pond picture taken with fisu and a couple of detail flaps taken from the hand on a small telescope.

I didn't seem to be able to wait in the yard to wait for the darkest moment of the night, but the camera came unloaded at home, and seeing this reportage, I'm still writing a quarter to two ... the show still seems to continue from the window, which is not surprising in itself.

Joo, vielä klo 2 näkyi alempein pilvien seassa kirkkaana itä/koillinen-sektorilla.   

Näköjään tänä kesänä saa olla valppaana noiden yöpilvien ilmestymisen kanssa.  Itse myöhästyin ja huomasin vasta klo 23.55.  Arpalahden Pentti näköjään on huomannut vajaata kymmentä minuuttia sinuakin aiemmin.   

Itse olin katsomassa ruskoa noin klo 23.20, jolloin ei vielä näkynyt.  Lopultakin yöpilvet tulevat näkyviin yllättävän nopeasti.
