USA 186 was reboosted on or about Jan.11, and around day 07081 its mean motion was equal to USA 161's. So with this average drag, the next reboost could occur another 70 days ahead, or day 07151 = May 31 Using more recent drag averages, Vec2TLE estimates the following elsets for that day: USA 186 1 28888U 05042A 07151.76918276 .00009005 00000-0 11161-3 0 16 2 28888 97.8935 213.9169 0523714 75.5856 290.2871 14.78974525 3516 USA 161 1 26934U 01044A 07151.74223489 .00002888 00000-0 53603-4 0 17 2 26934 98.0260 263.6512 0464467 261.0919 93.7457 14.78144843 3502 On its daytime pass at 50N, U188 would be 2:42 ahead of U161, and have a ground track about 9.6 deg E of U161's. So, U188 should indeed be close to a reboost. Note also that U161 perigee is near the equator, but it will not reach MM=14.8 until the end of 2007, so I doubt it will change its MM, only inclination? ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
