I have found another close encounter with one of the Iridium satellites.
This time it is between Iridium 14 (#24836, 97030A) and Spot 2 R/B
(#20443, 90005H).  Right now, the closest predicted approach is about
800 meters on Sept. 19 at 02:29:33.04 UTC -- only two hours from
now.  Here is the COLA output:

Target satellite: #24836
Name: Iridium 14
Perigee:   775.89 km   Apogee:   779.47 km

At the time of the encounter, the satellites will be over the middle
of the Indian Ocean at around geocentric latitude 41.54 S, longitude
84.76 E, altitude 793 km.  --Rob#026#
