All,

    The perigee Contacts were nominal. The sun maneuver was successful. I was not able to set the static z rate on this contact. The Star percent valid was only at 37%. The Hi instrument sweep table was commanded back to normal sweep. The Orbit 542 & 543 ATS’s were uploaded. The SSR was dumped and the 18 day timer was reset back to zero.
