My Decay Watch page now has the final notices for the latest two
decayers. In summary:
_____________________________________________________________________
Object: #27485 = 92- 41 F = Insat 2A Ariane 44L debris F
Decay predictions:
Source Prediction made Predicted decay at Latitude Longitude
UTC UTC deg deg
SCC Mar 19 06:28 Mar 18 21:21 +-6h 7.2 N 78.8 E
SatEvo Mar 17 21:00 Mar 18 21:06 +-8h 5.8 N 49.3 E
Final elset:
Insat 2A Ariane 44L deb F 1245 x 149 km
1 27485U 92041F 03076.75570162 .34446590 -23649-4 12326-1 0 2218
2 27485 7.2261 137.0423 0774791 9.9938 351.4759 14.58802286 16004
Note: This seems to have been lost throughout its last day and SCC's
final notice appeared only in the past hour or two. My previous
prediction remains unchanged, with my estimate being that it decayed
near Somalia soon after the end of the following predicted rev:
Insat 2A Ariane 44L deb F 394 x 126 km
1 27485U 92041F 03077.80870003 2.06231782 68370+1 62481-2 0 92186
2 27485 7.2183 129.0670 0202057 25.7571 335.2354 16.05279619 16162

Object: #27645 = 03- 2 D = ICESat Delta rocket
Decay predictions:
Source Prediction made Predicted decay at Latitude Longitude
UTC UTC deg deg
SCC Mar 18 13:36 Mar 18 12:54 +-32m 75.9 S 40.6 E
SatEvo Mar 18 21:40 Mar 18 12:38 -10+30m 29.7 S 70.4 E
Final elset:
ICESat Delta r 7.0 2.0 0.0 5.0 d 14 142 x 124 km
1 27645U 03002D 03077.49122424 .42390130 27635-5 31375-3 0 1527

Note: The final elset shows this running 20 sec early against my
final prediction. I estimate that this decayed southbound over the
Indian Ocean on the orbit given by this elset.
