A summary of the final notices for the two latest decayers from my Decay
Watch page:

Object: #11600 = 79- 93 A = Cosmos 1143
Final decay analyses:
Source Prediction made Predicted decay at Latitude Longitude
UTC UTC deg deg
SpaceCom Feb 17 19:10 Feb 17 19:05 +-7m 76.0 S 39.0 E
SatEvo Feb 18 19:20 Feb 17 18:48 +-50m 29.4 S 110.9 W
Final elset:
Cosmos 1143 5.0 1.5 0.0 5.4 v 14 154 x 140 km
1 11600U 79093A 02048.62703598 .17875946 -99961-6 31549-3 0 8363

Note: The final elset shows this running 3 sec late against my
predictions from the previous day. I put the decay southbound over
the eastern Pacific on the last of these SatEvo-predicted orbits:
Cosmos 1143 5.0 1.5 0.0 5.4 v 14 144 x 133 km
1 11600U 79093A 02048.68771501 .32030935 11197+1 34746-3 0 98365
2 11600 81.2041 133.8527 0008846 265.6108 94.2881 16.50312787223671
Cosmos 1143 5.0 1.5 0.0 5.4 v 14 125 x 119 km
1 11600U 79093A 02048.74826417 1.04315903 25924+2 48322-3 0 98369

Object: #23460 = 94- 87 F = Raduga 32 aux motor
Final decay analyses:
Source Prediction made Predicted decay at Latitude Longitude
UTC UTC deg deg
SpaceCom Feb 17 00:38 Feb 17 00:14 +-3h 45.8 N 136.4 E
SatEvo Feb 17 10:10 Feb 17 00:05 +-80m 44.2 N 103.3 E
Final elset:
Raduga 32 aux motor 445 x 100 km
1 23460U 94087F 02047.82907317 .68617433 11514-4 67703-3 0 3313
2 23460 46.3404 185.3969 0258979 71.6920 60.2432 16.00644843 80207
Note: SpaceCom seems to have lost this near the end, so the decay
remains uncertain by an orbit or more. The final elset has this 29 sec
early against my previous prediction. I now calculate the following
elsets for the final revs, with decay likely near, or even before,
perigee on the last of these:
Raduga 32 aux motor 315 x 95 km
1 23460U 94087F 02047.93055020 1.51547189 43653+1 94161-3 0 93315
2 23460 46.3327 184.7827 0167053 72.3074 289.5094 16.25278671 80228
Raduga 32 aux motor 141 x 80 km
1 23460U 94087F 02047.99133126 9.99999999 50000+2 22891-2 0 93310
2 23460 46.3293 184.4010 0046585 72.6899 287.8194 16.61021976 80232
This places it over Mongolia.
