That bright one you saw, moving slowly and fading, was probably an "Iridium" satellite. They have huge solar panels that relfect a lot of sunlight down to Earth when the angle is just right. They're so stable and predictable that the possibility of seeing any one of them from anywhere on the planet is predictable with fairly simple software.

I'm at my weekend overnight job (as opposed to my weekday one) so this computer doesn't have the bookmarks I want, but I'm sure some other friendly person here - like Raoul, for instance, our favorite Skywatcher - will post the URL to the best Iridium predictor.

Now I'm going out to see if the clouds have thinned... o.0
