The most recent elset has a reasonable mean motion, but a drag term that is much too small: 1 23805U 96012B 96063.16850579 .00012262 63816-9 79316-4 0 189 2 23805 28.4544 218.6829 0059140 247.3872 309.0707 15.72302267 1467 So this indicates that there has not been a break in the tether. I have reduced my drag coefficient by 5% and come up with: TSS/tether 1 23805U 96012B 96064.02156000 .00570000 00000-0 35000-2 0 00 2 23805 28.4651 212.5160 0050000 255.6050 104.6140 15.73700000 00 TSS/tether 1 23805U 96012B 96065.03573000 .00610000 00000-0 36500-2 0 00 2 23805 28.4651 205.1360 0047000 267.6230 92.5700 15.74900000 00 TSS/tether 1 23805U 96012B 96066.04910000 .00670000 00000-0 38000-2 0 00 2 23805 28.4651 197.7570 0046000 279.6410 80.5270 15.76210000 00 TSS/tether 1 23805U 96012B 96067.06158000 .00740000 00000-0 50000-2 0 00 2 23805 28.4651 190.3780 0044000 291.6590 68.4840 15.77640000 00 TSS/tether 1 23805U 96012B 96068.00989000 .00820000 00000-0 54000-2 0 00 2 23805 28.4651 183.4190 0043000 302.9920 57.1280 15.79130000 00 TSS/tether 1 23805U 96012B 96069.02038000 .00930000 00000-0 58000-2 0 00 2 23805 28.4651 175.9970 0042000 315.0800 45.0150 15.80920000 00 TSS/tether 1 23805U 96012B 96070.02964000 .01080000 00000-0 63000-2 0 00 2 23805 28.4651 168.5740 0040000 327.1680 32.9010 15.82950000 00 TSS/tether 1 23805U 96012B 96071.03748000 .01280000 00000-0 74000-2 0 00 2 23805 28.4651 161.1520 0038000 339.2560 20.7870 15.85330000 00 TSS/tether 1 23805U 96012B 96072.04366000 .01560000 00000-0 84000-2 0 00 2 23805 28.4651 153.7290 0035000 351.3450 8.6740 15.88190000 00 TSS/tether 1 23805U 96012B 96073.04780000 .02020000 00000-0 11000-1 0 00 2 23805 28.4651 146.3050 0031000 3.4340 357.3170 15.91790000 00 This is about 5 minutes later after a week compared to my post of an hour or so ago. There is still about that much uncertainty (if not more) in the prediction. Mike McCants mike@comshare.com
