A summary from recent updates to my Decay Watch page:
_____________________________________________________________________
Object: #1808 = 65- 98 D = Alouette 2 Thor Agena B deb
Final analyses:
Source Prediction made Predicted decay at Latitude Longitude
UTC UTC deg deg
SpaceCom Sep 24 00:29 Sep 23 20:14 +-1m 37.8 S 0.3 E
SatEvo Sep 24 21:50 Sep 23 20:07 +-20m 20.7 S 2.9 W

Note: I have this decaying southbound over the S Atlantic on the
orbit following the one given by the final elset.

Object: #11285 = 79- 20 A = InterCosmos 19
Final analyses:
Source Prediction made Predicted decay at Latitude Longitude

SpaceCom Sep 23 06:36 Sep 23 06:29 +-7m 16.0 N 45.0 W
SatEvo Sep 23 19:55 Sep 23 05:52 -15+45m 40.8 N 161.6 E
Final elset:

Note: I estimate that this decayed a little more than one orbit later
than the epoch of the final elset, possibly northbound over the NW
Pacific to the S of the Kamchatka Peninsula.

Object: #27379 = 02- 6 B = EchoStar 7 Atlas Centaur rocket
Notice prepared: 2002 Sep 25 07:00 UTC
Final analyses:
Source Prediction made Predicted decay at Latitude Longitude
UTC UTC deg deg
SpaceCom Sep 24 21:55 Sep 24 19:01 +-7m 22.0 S 110.0 E
SatEvo Sep 25 07:00 Sep 24 17:07 +-10m 22.5 S 114.5 E
Final elset:
EchoStar 7 Atlas Centaur r 1615 x 76 km
1 27379U 02006B 02267.66922162 .16378685 -46621-4 10000-3 0 899
2 27379 22.6029 113.8717 1065038 262.1483 135.2774 14.14178019 3006
Note: This decayed very quickly indeed when the perigee was forced
down by luni-solar perturbations; only three days before the apogee
was out at 28,970 km. The drag term in the final elset is a gross
underestimate, with the true value likely to have been in excess of
10.0 rather than the 0.16378685 given. My estimate is that it decayed
in the vicinity of perigee on that orbit, near North West Cape,
Australia.
