Comet C/2022 E3 is the greenish diffuse streak to the right of (a), taken on 10.02.2023 at 20:01 UTC in the constellation Taurus. It was of rather modest appearance.
(b) = Mars. Next to (c) is COSPAR 2010-043D = NORAD 37155, a Russian Briz-KM rocket upper stage that was launched from Plesetsk on 08.09.2010 and deployed 4 payloads. The altitude at the time the photo was taken was 1200 km, the distance 1320 km. This satellite was not visible to the naked eye. The streak at (d) is an even higher orbiting satellite, hence the shorter track. The scale is 1°, the exposure time was 10s at f/2.8.
