According to current elsets USA 129 is well placed within the operational constraints on pass time, now being 2h 22 m before USA 161 on the daytime pass. By coincidence (?) this reaches 2:48 on Jan.22 (2:45 on Jan.21). If USA 129 is apogee-raised one of those days, USA 161 would probably be raised on the same date to an MM 0.025 higher than USA 129's to put the next reboost as far into the future as possible. If the maneouvre is earlier, the difference should be smaller but in the same direction, and the raise of USA 161 can be postponed for the same effect - e.g. 1.5 days around Jan.12 to let the time separation grow to the maximum amount. /Björn > Arc 2002 Dec 25 - 2003 Jan 07 UTC: > > USA 129 15.0 3.0 0.0 5.3 v > 1 24680U 96072A 03007.58006564 .00030323 00000-0 33622-3 0 01 > 2 24680 97.8503 73.0085 0494505 172.7327 188.1417 14.83520696 07 > > WRMS error = 0.009 deg > > The object's perigee-crossing of the equator has passed without a manoeuvre.
