Update: I got pictures!
Astropixie notes that the Space Shuttle just undocked from the Space Station, and Jules Verne, the European cargo carrier, is just a few thousand kilometers away as well.
This means that if one passes overhead, you can see all three in a triple pass!
They'll be passing the US around 9:00 Mountain time. It's not hugely favorable for me in Boulder, getting only 23 degrees above the horizon. Worse, I have to look over the city of Boulder to see them, which means a bright sky. Still, I'll be looking. Check heavens-above.com to see if you'll get a good view too!
