The Space Shuttle and ISS flying in formation

Did any of you catch the 2 of them tonight?

Sorry I could not give you any advance warning, as I did not know when the space station and shuttle where going to separate. But as it happened, the shuttle pulled away from the ISS in preparation for its landing tomorrow. Thus the 2 crafts still follow almost exactly the same orbit, but a few hundred kilometers apart.

At about 7:30 this evening they both passed our skies at a low angle. The shuttle came by 1st at a magnitude of 0.7. The sky was still blue and we had a lot of blowing clouds here, but the kids and I did find it as it came out of the clouds heading northwest. Then about a minute later the much larger shuttle, and therefore brighter at magnitude -1.2, came zooming after it. I was very excited to have caught it (and the kids thought it neat too!). Actually this was the last visible pass of the ISS for the next 2 weeks.
