Congrats on your STS sighting, Joey.  Unfortunately, Mir isn't
continously sunlit anymore; That condition lasts less than
4 days, so it's too bad that the shuttle didn't launch on the
originally scheduled date in late May, which would have made
it possible for observers in lower latitudes to see more high
elevation passes.  As I write this, Mir enters eclipse at about
47N and exits eclipse at about 38S, so my STS & Mir passes are
currently low in the north, with bad phase angles.  For my
latitude the passes will get gradually higher in elevation as
the mission progresses, but I don't think I'll get good phase
angles.  I hope you folks at the higher latitudes have clear
skies and enjoy the show!

While I'm at it, here's an STS-91 elset obtained 06-03 08:00 UT from the
OIG website...
