The sky started to clear in the evening. At dusk a few scattered clouds.
From 20:51 UT till 21:25 UT a large patch of thicker clouds blocked the
view.
Then alernating scattered thin clouds and nice clearings. Also other larger
patches of thicker clouds causing gaps in the observations.
Despite this quite a few satellites could be imaged.
Conditions variating due to the thin clouds.
