The Starlink satellite 'Visorsat' (spacetrack #45713) was not seen on 2020 August 6 at 01:21:00 UTC. A star of magnitude 6.7 was clearly observed in the field of view so the limiting magnitude was around 7. The observation was made with 15 x 50 binoculars under slightly hazy skies. The satellite altitude was 482 km and its range was 502 km. According to the paper linked below, a regular Starlink satellite at that distance would be approximately magnitude 4.4. So, confirmation of this preliminary result would imply that Visorsat is, at most, only about 10% as bright as a regular Starlink satellite. https://arxiv.org/abs/2006.08422 Has anyone else observed Visorsat?
