Yet another update to my Decay Watch page...
_____________________________________________________________________
Object: #25032 = 97- 67 C = GPS 2-28 r2 (PAM-D)
Decay predictions:
Source Prediction made Predicted decay at Latitude Longitude
UTC UTC deg deg
SpaceCom Nov 5 08:47 Nov 9 09:10 +-3d 33.5 N 14.7 W
SatEvo Nov 6 21:20 Nov 9 19:43 +-22h
Latest elset:

Object: #25069 = 97- 75 C = JCSat-5 Ariane 44P rocket
Final decay analyses:
Source Prediction made Predicted decay at Latitude Longitude
UTC UTC deg deg
SpaceCom Nov 6 19:53 Nov 6 15:36 +-6h 4.0 N 108.3 E
SatEvo Nov 6 21:00 Nov 6 15:23 +-3h 3.4 N 66.4 E
Final elset:
JCSat-5 Ariane 44P r 603 x 108 km
1 25069U 97075C 00311.19659919 .34382328 -32074-4 56554-3 0 4160
2 25069 4.1623 292.1980 0367361 41.5358 319.4808 15.71142687 41834
Note: The final elset, one of four issued for that orbit, shows this
running 2.5 min late against the prediction I posted yesterday.
SpaceCom appears to have lost it well before decay. I show decay
near perigee on the second of these two SatEvo-predicted orbits:
JCSat-5 Ariane 44P r 296 x 95 km
1 25069U 97075C 00311.57121613 1.37901983 37803+1 75740-3 0 94162
2 25069 4.1608 288.9908 0153255 47.9249 313.3686 16.28913031 41899
JCSat-5 Ariane 44P r 157 x 90 km
1 25069U 97075C 00311.63187270 5.87964167 50000+2 14148-2 0 94161
2 25069 4.1603 288.4391 0051191 49.0239 311.4181 16.56074682 41905
This has it over the Indian Ocean, to the W of the Maldives. SpaceCom's
decay location is further E on the same rev, over Malaysia. The
uncertainty is several revs.
