This is my first post and I wanted to share with everyone my first satellite sighting. Tonight at 22:53 EDT I saw MIR and STS-91 fly overhead at a maximum elevation of 57 degrees. My location is 40.06 N and -75.05 W. MIR was ahead of Discovery by several seconds and even though I live in Philadelphia with all its city lights I was surprised at how bright it was. For other first time satellite observers out there, it was a lot easier to view than I had thought. If I could see MIR and STS-91 from the city with hazy skies, that's not bad!
