All,

   The Perigee contacts were nominal for CMD & TLM. The inertial maneuver was successful. We completed pass # 2 for CAR #1119 ISN Season. The Lo ISN sweep table “Table_Lo_11223678_ISN2” was loaded. The SSR was dumped twice. The Instrument ATS for orbit 510 and both Bus and INST ATS for Orbit 511 was uplinked. The 18 Day Timer reset command executed nominally. At Los the Timed Command count was @183.
