Greetings Ulhas, > What should be the lighting constraint set for geoflsh. If > I set 'no const' I get a large no of tracks but the moment > I set 'sunlit only' all tracks vanish. Leave the satellite lighting constraint at sunlit only, and change the magnitude limit to something like +13 or +14. That should show you plenty of GEOs (provided your range and perigee limits are set high enough in the All File search menu). The reason you need to set the magnitude limit so dim is that most GEOs never get brighter than 12th magnitude -- except when the specular component of their brightness swamps the diffuse return. SkyMap does not compute these "flare" magnitudes (near the equinoxes) because they vary too much from satellite to satellite.
