Here is a plot of magnitude normalized to 1000 km range vs. phase angle: http://satobs.org/seesat_ref/misc/10015A_std_mag_2.pdf The standard magnitude is 4.2 +/- 1 (1000 km, 90 deg phase angle). Coefficient of phase is 0.010 mag/deg. The object reaches magnitude 2 +/- 1 when observed at high elevation, and well illuminated.
