Hello,

OTM-3 was conducted yesterday in order to correct the ground track spacing.  The maneuver timing was as follows on DOY 223:

17:29:58 spacecraft began maneuver to burn attitude
18:09:30 spacecraft began turn back to Earth-point
18:21:30 spacecraft should be back in nominal attitude

Times are in UTC ERT.

The ground track spacing has been increasing rather linearly since it was set to 59 km with OTM-2.  This maneuver set the spacing to approximately 50 km.  The spacing will continue to increase at a rate of about 7 km per month until the next OTM.
