All,

    The Perigee contacts were nominal. The inertial maneuver was successful. The Orbit #549 Lo Gain Cal and the Orbit # 550 ATS’s  were uplinked. The Flight Computer Back Orbit buffer and the SSR were dumped. I was not able to complete the full SSR dump since I was at the 160k Downlink rate. At LOS the SSR read pointer was at 38430 & the remaining blocks were at 4178.
