Re: Figuring out a satellite.
Pull up heavens-above.com, and feed in your location. It generates a list of visible satellites and times from that location, down to 4.5 magnitude. If you can match the trajectory and time of your observed satellite with a satellite on that list, you have it nailed. There are quite a few in polar orbits.
The website can be made to remember your location so that it will automatically load when you check in.
