Ran my AllSky Camera again from Kelling Heath at the Equinox Sky Camp and on Friday 13th Oct. 2023 and got an even better time-lapse video showing large numbers of geostationary satellites above naked eye visibility.
Have done a crop of the Southern sky which includes the UT clock at the left hand edge: Video can be found at: https://www.youtube.com/watch?v=zOrSYaT4rgQ
For those interested, the geostationary satellites are in a band half way up the screen in the time lapse video. They are at the anti-solar point which starts at the left hand side and moves to the right as the night progresses. At 00.27UT, 45 secs in, about 9 satellites are seen in a swarm with some flaring to mag ~2.
Cheers
