Basically a repeat of Is Starlink 1130 (Darksat) really dimmer? but this time with Visorsat.

What is the observed brightness of VisorSat(s) and is it dimmer than non-Visorsat Starlink satellites?


Initial observations of the Visorsat put it a mag 7 in final orbit; however larger collections of observations from amateur sat watchers put it at ~mag 6. Since then further observations by astronomers indicates a mag of 6.5. This represents a 2 mag reduction from Starlink which is ~mag 4.5, however it is still short of mag 7 requirement set by LSST. (speculation: the mag might've been reduced between the initial observations and the astronomer observations with improvements to orientation during orbit and it might be able to reach mag 7 reduction, however it also might require further hardware brightness reduction.)

  • $\begingroup$ "Initial observation" suggests a positive identification of the satellite. That's maybe too strong to describe that message which boils down to we didn't see it but should have been able to see objects as faint as magnitude 7. $\endgroup$ – user2705196 Aug 10 '20 at 13:07
  • $\begingroup$ I can't +1 again for all the extra effort. You might consider asking a separate question about the part that seems "Confusing AHAHSAGDH" :-) $\endgroup$ – uhoh Sep 7 '20 at 13:10
