A note to all potential STS-63 trackers: These elemets are still preliminary. The actual time of liftoff will be determinted during the last major hold about 1h 30m before launch, and based on state vectors for MIR. If everything goes according to plan, these elements will be "valid" from the time of the OMS-2 burn (if needed) to rev 6, when the first trim burn to transfer to the MIR orbit takes place. Those of you in England looking for the shuttle should remember that the flight profile of a launch places the shuttle at an altitude of some 67 nm at MECO... it then follows an eccentric orbit out to about 180 nm half a rev from Florida, where they initiate the OMS circularization burn. It will therefore probably be lower and sooner than the current preliminary Keps would indicate.

The shuttle and External tank should be visible. It also looks like Mir should preceed the shuttle by 10 min or so, although the exact time will depend on the latest elements. Great viewing opportunity indeed!
