I just found a site that might interest those of you who are scientifically minded. It helps you follow the progress of various satellites such as the International Space Station. Many of these are visible to the eyeball observer if you know where and when to look. As the ISS gets bigger, it becomes easier to see. As I write this, it is over South Africa. Check out www.spaceflight.nasa.gov/station
I'm going to put it down there as a link, but sometimes I don't get them to work. Maybe my luck is improving.
