Flashmail I agree, although MetOp-A alternates between normal and negative drag in a sawtooth pattern. This drag/slow orbit correction is so small that it takes about four weeks for a +drag elset to be 21 sec late wrt the previous -drag one. But the cycle is about 2.3 days up, 2.3 days down, so compared to reality the +drag elset must be >6 weeks old to show this discrepancy. No sudden MM jump has occurred in the last two weeks. So if you verified that H-A used a 04 Sep elset, with MM=14.2149..., I suggest your timing was off, or you saw a "red herring" (different object) 06-44A 29499 METOP-A should have passed 3' ABOVE 11 Per 19:38:49 81-65B 12586 SL-3 R/B 16' below 11 Per (HP061292) 19:39:09 /Björn ----- Original Message ----- From my place, 2006-044 A MetOp-A passed, on september 4th, 0°2 below the star 11 Per at 19h39m08s UT, that is 21 seconds later than expected from the Heavens-Above charts (for epoch 4sep). Rather an unusally large time delay. ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
