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.)
