I dust off STSPLUS and i remember this program give the pass where the satellite is visible. It works very well with ISS and the shuttle
The magnitute of AO-51 is the key here try STSPLUS il will give you the time and the orbits where AO-51 is visible. Again the V visible
mean the sun is illuminating the satellite. but this does not confirm that the satellite is really visible. . It works for ISS but i think
not for AO-51. At least the you will not have to watch each and every pass to get the right one.
