It would seem there are two possible canidates involved in the recent near 
miss of the CHRISTA-SPAS sat. These two PAM-D sats come from the failure to 
place the Palapa B2 in geo-sync orbit from the Feb 1984 launch of Challenger 
(41-B).

If anyone has a COLA (Collision Avoidance) prediction program could you run 
a pass ( I assume for Aug 12) using these elements and see what you come up 
with?
