This is the latest element set for what is in all probability
Amsat-Oscar-10.  There is very little radar data on this object,
primarily because it is so small.  However, it gave a good LOS
prediction time for Tokyo earlier today, so it is probably good for
tracking.

Object 14129 - probably Oscar-10:
Epoch time:      83170.50000000
   Sun Jun 19 12:00:00 1983 UTC
Element set:         MH 6-22-83
Inclination:        8.5590 deg
RA of node:       248.1490 deg
Eccentricity:    0.7288272
Arg of perigee:   180.3280 deg
Mean anomaly:     313.5510 deg
Mean motion:    2.29924800 rev/day
Decay rate:          0.001 rev/day^2 (poorly determined, probably too large)
Semi major axis: 24253.381 km
Anom period:    626.291727 min
Apogee:          35551.760 km
Perigee:           198.712 km


One AMSAT command station has done some ranging, but there is not yet
enough data to properly define the orbit.
