#7969 = 75- 56 B = Cosmos 744 rocket No further elsets were issued after I posted a note with my prediction of the imminent decay of this at Jan 22 16:55 +-90m. If it had survived, the track would have taken it near Los Angeles and San Diego at 17:03 UTC, Las Vegas at 17:04, Boise, Idaho, at 17:06 and Calgary, Alberta, at 17:08. However, there are only negative reports from this area (for which, thanks). In its subsequent final decay notice for this, SpaceCom reports a decay time of Jan 22 16:56 +-44m at 15.0 S, 123.1 W. the final elset was: Cosmos 744 r 3.8 2.6 0.0 5.1 v 11.1 138 x 126 km 1 07969U 75056B 00022.65461921 .18086513 -86473-6 13593-3 0 781 2 07969 81.2355 253.7183 0009619 160.9935 257.5662 16.52740985354152 #13964 = 83- 25 A = Molniya 1-57 This decay has slipped sharply over the past day, a feature I have noticed before with decaying Molniyas and something I have suggested might be due to the detachment of solar panels during the stresses of deep perigee passes. This would have the effect of reducing the cross- sectional area and the drag, at the expense of only a relatively small reduction in mass. I now show decay at Jan 24 08:27 +-12h while SpaceCom has joined in again with Jan 24 07:33 +-1d. #26044 = 99- 73 C = Cosmos 2368 Molniya platform This probably came down a little more quickly than I expected near the end. My prediction for the final orbit is: C 2368 Moln pl 3.0 0.0 0.0 5.5 d 9 146 x 118 km 1 26044U 99073C 00022.16668769 .61578710 39514+1 37155-3 0 90976 2 26044 62.8100 235.9057 0021613 118.0425 242.1763 16.52850146 4030 I think that the decay was most likely as it approached the end of this rev, possibly on a track over Africa from southern Namibia at 05:19 UTC to its northbound equator crossing near Lake Victoria at 05:27. The nominal decay time I calculate is Jan 22 05:20 +-1h near 25.4 S, 20.8 E. SpaceCom puts the decay further S, at Jan 22 05:14 +-1h and 57.7 S, 16.7 W, but both predictions are consistent given the one hour uncertainties.
