Ignoring it, I get a decay rather close in time to the epoch of the final elset with the object northbound to the W of Mexico on a track that would take it to Yuma, Arizona, at 08:12 UTC and onwards over Utah and Wyoming to North Dakota (08:17). _____________________________________________________________________ Object: #26215 = 99- 57 DD = CBERS 1 CZ-4 rocket debris Decay predictions: Source Prediction made Predicted decay at Latitude Longitude UTC UTC deg deg SCC Dec 11 19:43 Dec 13 19:56 +-1d 59.3 S 137.2 E SatEvo Dec 12 20:00 Dec 13 14:19 +-12h 25.4 N 157.8 W Latest elset: CBERS 1 r DbDD 1.0 1.0 0.0 7.5 d 1.2 294 x 273 km 1 26215U 99057DD 02345.97543102 .03293612 14197-1 93674-2 0 9542 2 26215 98.5395 140.9606 0015663 324.9569 35.0665 15.96663235148747 SatEvo prediction: See Decay Watch page.

My estimate is for decay just after passing over the Hawaiian Is on the orbit after the final predicted one above. _____________________________________________________________________ Object: #27517 = 02- 42 C = DRTS H-2A r Decay predictions: Source Prediction made Predicted decay at Latitude Longitude UTC UTC deg deg SCC Dec 11 22:53 Dec 11 22:44 +-7m 30.0 S 79.0 E SatEvo Dec 12 20:15 Dec 11 22:28 +-20m 14.5 S 11.3 E Final elset: DRTS r DPAdpt 1.5 3.0 0.0 6.0 d 5 156 x 151 km 1 27517U 02042C 02345.90096935 .57055263 -49874-5 20186-2 0 1627 2 27517 30.3822 223.0871 0004276 195.9065 164.5322 16.44701409 14452 Note: I show this decaying following the southbound equator crossing on the above orbit, putting it just to the W of Angola. _____________________________________________________________________ Alan -- Alan Pickup / COSPAR 2707: 55.8968N 3.1989W +208m (WGS84 datum) Edinburgh / SatEvo & elsets: http://www.wingar.demon.co.uk/satevo/ Scotland / Decay Watch: http://www.wingar.demon.co.uk/satevo/dkwatch/ * ----------------------------------------------------------------- Unsubscribe from SeeSat-L by sending a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@lists.satellite.eu.org http://www.satellite.eu.org/seesat/seesatindex.html
