A new analysis, using just the final three elsets, again leads to decay at 22:42 UTC. However, this would imply that it was still in orbit when it flew down the length of California and Arizona only minutes earlier. If this was so, I am very surprised that no elset was generated for that rather critical orbit - it should have been along the lines of: Telstar 6 Proton r 134 x 115 km 1 25627U 99005B 99047.91702511 .61258585 76775+1 26808-3 0 90180 2 25627 51.5934 222.4929 0014313 278.0780 81.7596 16.55659068 271 After all, elsets had been released for seven of the previous eight orbits. I speculate that it may, indeed, have decayed prior to 22:30, before it reached the west coast of the USA. --------------------------------------------------------------------- Object: #13103 = 82- 6 C = OPS 2849 deb Decay predictions: Source Prediction made Predicted decay at Latitude Longitude UTC UTC deg deg SpaceCom Feb 12 13:04 Feb 19 10:40 +-4d 54.5 S 91.1 E SpaceCom Feb 14 22:09 Feb 18 19:47 +-2d 33.5 S 36.1 W SpaceCom Feb 15 20:59 Feb 18 21:26 +-2d 74.8 S 84.4 W SpaceCom Feb 16 20:55 Feb 18 20:46 +-1d 82.3 N 29.6 E SatEvo Feb 12 19:40 Feb 21.1 +-3d Note: Still no published elsets since that for 99041.17 --------------------------------------------------------------------- Alan -- Alan Pickup | COSPAR 2707: 55d53m48.7s N 3d11m51.2s W 156m asl Edinburgh | Home: alan@wingar.demon.co.uk +44 (0)131 477 9144 Scotland | SatEvo page: http://www.wingar.demon.co.uk/satevo/
