In a warning dated 2088 February 20, SpaceCom is predicting the decay of #22 = 59- 9 A = Explorer 7 on 2088 February 27 at 01:22 +-2 min. Some mistake, I suspect. Otherwise, from my updated Decay Watch page... _____________________________________________________________________ #10362 = 77- 91 A = Cosmos 955 Final decay analyses: SpaceCom: Sep 7 19:07 +-51m 38.7 N 37.5 W SatEvo: Sep 7 18:58 -20+30m 19.8 N 40.3 W Final elsets: Cosmos 955 5.0 1.5 0.0 5.4 v 24 141 x 124 km 1 10362U 77091A 00251.72658542 .24099736 00000-0 18090-3 0 6160 2 10362 81.1767 228.2965 0012902 233.0568 127.0179 16.52481185261781 Cosmos 955 5.0 1.5 0.0 5.4 v 24 138 x 134 km 1 10362U 77091A 00251.73738821 .16256400 -88171-6 16341-3 0 6174 2 10362 81.1625 228.2676 0002405 108.0005 316.2839 16.51290804261787 Neither of the two final elsets appears perfect - the first may have a too-high eccentricity and the second indicates an unlikely shift in the perigee around the orbit. The two orbits differ in equator crossing time by 1.5 sec, being respectively 0.02 sec (!) early and 1.5 sec late with respect to my final pre-decay prediction which satisfied the previous 7 elsets with a mean residual of 0.09 sec and a maximum residual of 0.24 sec. The final elset of this prediction is: Cosmos 955 5.0 1.5 0.0 5.4 v 24 131 x 127 km 1 10362U 77091A 00251.72655319 .63055520 56252+1 42015-3 0 96157 2 10362 81.1717 228.2932 0003463 223.9331 136.0394 16.53980418261781 I show this decaying northbound over the Atlantic to the north of Brazil. _____________________________________________________________________ Object: #14693 = 84- 11 E = Palapa B2 r (PAM-D) SpaceCom has not renewed its estimate for this decay to occur on September 9, which must be an error. My current estimate is for September 24 +-6d. _____________________________________________________________________ Alan -- Alan Pickup / COSPAR 2707: 55d53m48.7s N 3d11m51.2s W 156m asl 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://www2.satellite.eu.org/seesat/seesatindex.html
