Cees Bassa and Peter Wakelin have just posted observations that revealed the object running more than 6 min. late relative the epoch 14365.72708333 orbit. It appears to have made a major manoeuvre near the passage through perigee of Jan 02 at 07:36:51 UTC. Anchored by a synthetic observation at the perigee of manoeuvre, the new observations yield the following solutions. For this one, perigee distance was held constant: USA 259 2131 X 38065 km 1 40344U 14081A 15002.77259259 .00000000 00000-0 00000-0 0 06 2 40344 62.8372 210.5672 6786203 266.7212 330.3265 2.01515330 08 Arc 20150102.32-0102.77 WRMS resid 0.011 totl 0.002 xtrk For this one, there was no restriction on perigee height: USA 259 2143 X 38055 km 1 40344U 14081A 15002.77259259 .00000000 00000-0 00000-0 0 06 2 40344 62.8403 210.5630 6781608 266.6870 330.3026 2.01497598 00 Arc 20150102.32-0102.77 WRMS resid 0.009 totl 0.003 xtrk For both solutions, argument of perigee was held constant at the pre-manoeuvre value. The remaining manoeuvre(s) to reach ~2.006 rev/d can be expected to occur over the coming several days.
