To conclude the story of our latest two decayers...

Object: #26499 = 00- 31 E = Express 3A aux motor
Final decay analyses:
Source Prediction made Predicted decay at Latitude Longitude
UTC UTC deg deg
SpaceCom Jan 21 02:28 Jan 21 01:18 +-55m 33.3 N 151.9 W
SatEvo Jan 21 10:05 Jan 21 01:05 +-30m 46.6 N 164.8 E
Final elset:
Express 3A aux motor 669 x 88 km
1 26499U 00031E 01020.99044510 .99999999 10146-4 21780-2 0 1618
2 26499 46.5767 205.7140 0430056 84.1935 53.8595 15.63319478 5203
Note: This probably decayed near perigee on the following orbit which
would place it eastbound over the northern Pacific. A very approximate
SatEvo-predicted elset for the start of that rev is:
Express 3A aux motor 381 x 78 km
1 26499U 00031E 01021.02958780 8.77481756 50000+2 26049-2 0 91619
2 26499 46.5589 205.4860 0229000 84.4196 278.1876 16.16382334 5213

Object: #26665 = 01- 1 B = Shenzhou 2 Long March 2F rocket
Notice prepared: 2001 Jan 21 10:25 UTC
Final decay analyses:
Source Prediction made Predicted decay at Latitude Longitude
UTC UTC deg deg
SpaceCom Jan 20 11:33 Jan 20 10:19 +-1h 40.6 S 55.9 W
SatEvo Jan 20 09:20 Jan 20 11:35 +-45m 41.3 S 116.0 W
Final elset:
CZ-2 R/B 10.0 4.0 0.0 2.0 d 40 154 x 127 km
1 26665U 01001B 01020.31893176 .21032225 89836-5 19674-3 0 580
2 26665 42.5420 286.8287 0020640 229.3860 130.7186 16.49538073 1718
Note: The final elset was the only one to appear during the final
~14 hours of this decayer. My analysis, that this decayed southbound
over the SE Pacific, is unchanged although this is almost a full
orbit later than SpaceCom's estimate. My predicted elset for the
final rev is:
CZ-2 R/B 10.0 4.0 0.0 2.0 d 40 128 x 113 km
1 26665U 01001B 01020.43973731 .50825293 29179+1 18292-3 0 90589
2 26665 42.5402 286.0029 0011458 230.3466 129.5522 16.57158806 1738
