All,

  The Perigee passes were nominal for CMD and TLM and the inertial maneuver was successful. We dumped the SSR and set the read and write pointers to 70000. Between the 2 passes, the Star Tracker went thru an autonomous reset. The time of the reset was Feb 10 @21:26:55z. During the second pass I reset the latch values and FDC totals (CAR #1023).



The following was also accomplished during the perigee passes:

Reset the master timer

Reset FDC totals

CAR 1022 ATS upload - IBEX_2019_051_o0438a_v001 93 cmds

Dumped the Flight Computer Back Orbit data
