  The mean visual magnitude of OneWeb satellites at the standard satellite
distance of 1,000 km is 7.18 +/-0.03 . When this value is adjusted to the
nominal 1,200 km altitude of a OneWeb satellite in orbit it corresponds to
magnitude 7.58 which is an indication of the mean brightness at zenith. The
OneWeb satellites are fainter than the original Starlink satellites at a common
distance. Preliminary data on the new and dimmer VisorSat design for Starlink
suggests that they are still brighter than OneWeb at the satellites' respective
operational altitudes.
