Hi everybody,

In an article by Z.N.Khutorovskiy et al., 'Collisions of 
Space Objects on Low Orbits', published in 'Collisioons in
Surrounding Space (Space Debris)', Moscow, Cosmosinform, 1995,
a table is presented of five calculated dangerous encounters
of space objects with the Mir space station in July 1992 
through August 1994, see abridged version of the table below.

Date    Time UTC Russ ID     i    Hp   Ha   d    dv   size  Object
1992.11.08 10:18 83-111-1  82.9  399 1806  0.3  12.7  2.5   Kosmos-1508
1992.11.17 16:38 87-012-7  30.8  369  413  2.2   7.7  0.50  Ginga Deb
1994.05.24 18:33 6728      81.2  415  447  1.4  11.7  0.16  ?
1994.08.08 07:54 6728      81.2  415  447  1.9  14.1  0.16  ?
1994.08.20 21:50 91-017-2  68.0  390  530  1.9  13.2  4.3   Lacrosse 1 R

Here d is minimal distance, kilometers, and dv is relative
velocity, km/sec. Unit of size unknown, probably meters.

Object 6728 is an unidentified object in the Russian catalog,
and it did encounter Mir twice.

According to the article, the most dangerous encounter occured 
on Nov 08, 1992, at 10:18:01.2 UTC.

Would anybody like to comment/check/etc.?
