Thanks Steve, for the Mir/Shuttle obs. >Observed STS-86 and Mir at 23:25 UT on Oct 3. >Mir leading , mag -1 to -2. Atlantis following, mag 0. >Steve Bolton The latest elsets from OIG that I just got show Atlantis leading. Could they have switched positions, or is it another case of mistaken identity? They can be difficult to tell apart sometimes, although Mir generally has a more yellowish tinge than the pure white (and black, of course) shuttle.
