International Space Station flyover, about 6:40 PM, 9 December 2012, as advertised on Satellite Flybys by spaceweather.com:
ISS 06:41:00 pm SSW 06:44:09 50° -3.3 (very bright)
It was indeed very bright, as bright as Jupiter, which you can't see in the video but which had risen in the east. When the space station got within about 15 degrees of the eastern horizon, it faded out, turning orange first, as you can see in the video. Sunset on the space station!
Here's the video:
