The space station went over the Washington, DC, area last night. I've seen it a few times, but this was the best ever. There were a few clouds in the sky, and I didn't pick up the station until it was 30+ degrees above the horizon. It looked like a moderately dim star (by DC light pollution standards) but gradually brightened to probably a slightly negative magnitude as it went almost directly overhead.
It was just barely after sunset, and I could see the station until it disappeared behind some trees on the southeast horizon, having faded considerably from its peak brightness. That's the first time I've been able to follow the space station for that long - on other occasions it's gone into shadow shortly after passing overhead.
The place to go to find out if anything interesting is passing overhead is http://www.heavens-above.com, though actually I heard about this event on the radio, surprisingly enough.
