Closest approach for Cosmos 2321 (Norad #23676) was on 6/6/97 at 6:23:21.1 UTC
at a range of 2.9 km.  Closest approach for Aureole 2 (Norad #7003) was at
11:31:14.5 UTC at a range of 3.7 km.  Cosmos 2321 was below Mir, about 35
degrees from nadir; Aureole 2 was above Mir, about 20 degrees from zenith.

Based on the following elements for #23281 (1994-061C, Cosmos 2292 Deb C),
this object will come within 2.2 km of Mir on Tuesday, June 10th at 6:43:58.4
UTC.  Nadir angle from Mir is around 60 degrees, which means 1994-061C will be
about 1 km lower than Mir at the time of closest approach.
