Operations CXO Status Report

Friday 9 September 2005 9.00am EDT

During the last week the observing schedule was interrupted following a high radiation event at 11:44pm EDT on Sept 7 that stopped the daily load and activated the science instrument safing sequence (SCS 107). All actions were nominal and loads will be restarted once radiation levels have dropped sufficiently.

A real-time procedure was completed on Sept 8 to uplink a maneuver-only load to ensure an attitude that will minimize momentum buildup.

The schedule of targets for next week is shown below.
