Derek Breit and Alberto Rango reported USA 186 (05042A / 28888) running late last night (Jul 15/16 UTC), indicating that it has made the expected small reboost manoeuvre. Alberto has reported three positions, based upon which, I have narrowed the likely manoeuvre times to the perigee passages of 15:25:57 UTC and 17:03:07 UTC, on Jul 15, resulting in the following elements: 20090715 17:03:07 manoeuvre 1 70001U 09196.83375569 .00008435 00000-0 78720-4 0 00 2 70001 97.8831 259.2430 0539121 69.7912 296.0419 14.77037686 06 20090715 15:25:57 manoeuvre 1 70002U 09196.83375580 .00008438 00000-0 78720-4 0 07 2 70002 97.8831 259.2426 0537006 69.7912 296.0199 14.77500747 00 The 70001 elset is in closest agreement with Derek's report that the object was 55 s late. I will revise the elements upon receipt of Derek's data.
