I have run the program "COLA" for upcoming close passes for the Mir Complex and have turned up the following. On Sept. 15, 1997 at 20:33:30.1 UT, the Mir Complex may come within 3 km of an object #23101 (MSTI 2) of RCS 1.2 sq m. Is this calculated close encounter significant or just nothing? As the Mir is traveling at about 7 km/sec. then the margin for error is about 0.5 sec. I do not have a good appreciation for the acceptable tolerances in these matters but I just thought I would mention it. Jeremy Ollerenshaw jolleren@ix.netcom.com
