All,
    The perigee contacts were nominal for CMD & TLM. The Inertial maneuver was successful. The Orbit 523 Hi Gain Cal ATS and the Orbit 524 Bus ATS was uplinked. The spacecraft clock was set. I was also able to redump the missing data from Orbit #521. The 18 day timer reset command executed nominally. The number of timed commands onboard at LOS was 203.
