I too saw the pass of Mir and Shuttle on Oct 3 at roughly 23:23 UT from my location in Raleigh, NC. It was the only pass that I have seen with Mir and Shuttle together and so close - they were about 10 degrees apart, the Shuttle leading and slightly lower. The shuttle passed below Jupiter in the SE and Mir passed above it shortly after. They were both around mag -2 the whole time but Mir flared to around mag -3 just past Jupiter (judging that off the fact that Jupiter is approx. 2.5). It was so neat because it gave a 3 dimensional perspective to the pass as both sunk down towards the horizon, you could really tell they were following each other. Very cool.
