Dim night shining clouds - 5.8.2021 at 00.53 - 5.8.2021 at 03.20 Helsinki Observation number 100223

Visibility II / V


There was a negative when approaching one, but at the observation point, where the horizon is at about 3 degrees, a thin belt appeared on the back screen (Fig. 2). Then one had to believe and after twenty minutes the graceful patterns rose higher between north and northeast to a height of about 10 degrees. The brightest area somehow stood out visually, though adjoining a wide variety of lamps.

Edit. And the show continues for more than three. Left behind a tree and a house, but would appear to be brighter on the northeast side to a height of 15 degrees. Yes, you have time to get involved in these long shows.

Jaa-a, tein viimeisen havainnon klo 1.08, mutta ilmeisesti havaintohorisontti ja kännykän tarkkuus ei riittänyt huomaamaan noita.
