Hi Kevin, Orbitron is a great little utility and it will calculate look angles for you (http://www.stoff.pl). As these are not 'passes' in the conventional sense, you can't generate predictions, but if you select the objects in your region from the geo.txt TLE, it will show the Az / El as in the sample below (0130 UTC) and you can flip from one to the next very quickly. Assuming geosat visibility follows the normal rules (sun's centre between -6 and -18 degrees below observer's horizon), this should guide you for best viewing time.
