I have analyzed the 24 positional observations reported to-date that include visual magnitude. Here is a plot of magnitude normalized to 1000 km range vs. phase angle: http://satobs.org/seesat_ref/misc/10015A_std_mag.pdf The standard magnitude is 4.6 +/- 1 (1000 km, 90 deg phase angle). Coefficient of phase is 0.0082 mag/deg. This result is similar to the 4.8 standard magnitude I estimated pre-launch from the object's known dimensions. The object reaches magnitude 2.5 +/- 1 when observed at high elevation, and well illuminated.
