Abstract
The mean of 430 visual magnitudes of VisorSats adjusted to a distance of 550-km (the operational altitude) is 5.92 +/-0.04. This is the characteristic brightness of these satellites when observed at zenith. VisorSats average 1.29 magnitudes fainter than the original-design Starlink satellites and, thus, they are 31% as bright.
If you looked at the night sky in the last 10 years you already saw satellites and second stage rockets in orbit many times during the night, even in a light polluted area. Here's a study https://arxiv.org/abs/2101.00374 that looks at Starlink satellites with the visor. Looks…
