Operations CXO Status Report

Friday 22 May 2015 9.00am EDT

During the last week the observing schedule was replanned to incorporate an observation of MXB1730-335, which was accepted as a Target of Opportunity on May 21. Scheduled observations of Swift J145440.2-5135 and NGC 5033 were impacted by the replan and will be rescheduled in future weeks.

A real-time procedure was executed on May 19 to uplink a flight software patch that updates PCAD constants which affect the gyro bias vector when the PCAD software initializes. Additional real-time procedures were executed on May 19 to dump OBC-A memory as a follow-up to the patch. The dump will be used to update the baseline memory image maintained on the ground.

The schedule of targets for the next week is shown below and includes M28 coordinated with NRAO-GBT.
