If you have Sienna Software's "Starry Night," you can do some extra checking on
the candidates that Bjoern provided.  For example, I used the "Goto" feature to
"hop on board" Mir at the designated time, and from there I looked directly at
the sun (using my virtual mylar glasses, of course :-)), and ran the clock
bacwards and forwards.  I saw that from this vantage point the moon nearly, but
never quite totally, covers the sun--which indicates that Mir will not quite be
eclipsed.  This of course might change as updated TLE's become available.
