Bluewalker 3: magnitude data

Below magnitude data for Bluewalker 3 (2022-111AL) are from photometry on video 
imagery captured during a near-zenith pass near the end of twilight last night, 
using a WATEC 902H2 Supreme and Pentax 1.2/50 mm lens.

Each reported Vmag is a running average of measurements on 5 frames.
The 'Rmag' output of the camera has been converted to Vmag using an empirical 
equation, that is based on measuring a large number of reference stars and 
mapping the measured 'Rmag' to the star's catalogue Vmag.

Data are from the ascending part of the pass: I lost the satellite during the 
zenith traverse, as I had to turn my camera 180 degrees and failed to re-acquire 
the object (partly because I initially latched onto the wrong object, a Starlink 
- they really start to be the vermin of the sky).

Sky conditions were good.
