A much simpler way to casually view a schedule for sighting the Space Station is to go to.... http://www.spaceflight.nasa.gov/realdata/sightings/ and click on a city of your choice. Have fun. You might also listen on 145.82 Mhz (FM) for their ham station. It is easy to hear even with a scanner & 1/4 whip, when they are within range. Jess KR4OJ
