Visibility IV / V
An interesting play, unfortunately very cloudy after the beginning. recorded with an all-sky camera. Before 20:00 we (Veikko, Juha and Tuija) went to visually follow the repos in the north. Toni Veikkolainen filmed and reported himself. Kari was the first to notice the flares from the all-sky camera while photographing asteroids.
At 18:56 The first storms to the north-east into the dim sky.
18:56-19:11: First wave. A greenish arch rises from the northeast, a reddish repo to the front at 7:04 p.m., also progresses to the southwest. At 19:08 the green passes the red, the red sharpens and branches.
From 19:11 to 19:25. Second wave. We go out for sure without seeing anything visually, even though the arcs are clear on the camera. The first green fades at 19:14, the red remains visible. We doubt whether the red is caused by the LEDs on the observation platform, which turns out to be a false conclusion. At 19:13 a new green appeared to the northeast and red in front of it. At 19:21 green, ahead of red, advanced to the zenith and red forms an arc. At 16:24 the green passes the red and reaches the first red arch at 19:25.
At 19:31-40. There was a 5 min break in the camera. The latter red is faintly visible and disappears. The green glow of the south is gone. Traditional repos have appeared in the north. Visually green, the camera also records red. We go to look at the logging hole.
At 7:40 p.m.-56 p.m. Calm rays in the north, brightening/dimming (qR2R2-3c). Wide green glow (qHV2c) over the zenith. At 19:45 thin clouds over. The camera shows that the play is spreading well to the south.
From 19:56 to 21:00. Visible from behind the clouds as the brightness varies.
At 21:00-21:40 At 21:06 transverse structures in the aurora borealis from behind the clouds. They are visible until 21:33. Maybe dunes? A word of caution: the cloud cover may be affected. The direction of the clouds is southwest-northeast, so the streaks may be real. Later, however, an east-west cloud will also appear.
At 21:40-22:10 In the north, horizontal structures in the north, this time the clouds are probably the culprits.
At 22:10-23:15. The cloud mass thickens, with occasional patches until 23:15.
