Too much depends on the geometry the current pass (elevation, azimuth,
orbital height, time, season, latitude ...) . To avoid the most cases
of disappointment,  the only workable answer is using a magnitude
prediction program like SkyMap, QuickSat, SeeSat, ViewSat - though
only the last two use the same intrinsic magnitude info (Molczan)

Still, a lot depends on the satellite's own geometry and attitude.
