If anyone is interested in Visually seeing the ISS down load satscape it is freeware satelite tracking software. You will need to update the KEPS after you download it. KEPS is the satelite tracking info. the program will do it with a push of a button. I have saw the spacestation 3 times last month. it look like a very very bright airplane with no flashing lights usually you have to wait about 5 minutes after what the program says because it starts when the ISS breaks over theharizon and it will have to get fairly high for you to see it. believe it or not the solar panels are so big on the thing and if everthing is right it will work like a big mirror you should be able to watch it go over for several minutes you will know it if you see it.
I talked to Mir space station several years back and iam waiting to get a chance to talk to the ISS when the get all there amature radio equipment back up and running. anyone wanting to try and see this i will be glad to help all i can and here are some sites before i go.
you can also have the times at which you can see the spacestation emailed to you some months you may only get one email a month, remeber everthing has to be just right to see it.
