All,

   The perigee contacts were nominal for CMD & TLM. The inertial maneuver was successful. The 18 day timer reset back to 10 as commanded. The Orbit #515 ATS’s were uplinked. The SSR dump was successful. The SSR had 53935 blocks to be dumped. I was able to dump the complete set during the USHI01 @02:00.
