Everyone should know about this website.
This site tracks the positions and predictions for all the satellites in our orbit. Including the shuttle, the space station, and a group of satellites known as iridium flares. I have no idea if you city folks would have much luck, but it's at least worth a try, the flares especially are brighter than any star. I love seeing the shuttle and the space station, it's such a rush to realize that the tiny dot floating past is really people out there doing their jobs. The flares are cool because there are a lot of them, so you can see them several times a week. It's like a slow shooting star that's brighter than anything you've ever seen in the sky. Negative numbers are brighter, there is a -6 tomorrow night at 7:10 from my location that I really hope to see. Your global position makes a difference so log on and find your area.
