Operations CXO Status Report

Friday 20 May 2016 9.00am EDT

During the last week Chandra completed the observing schedule as planned.

A real-time procedure was executed on May 17 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 17-19 to dump OBC-A and -B memory as a follow-up to the patch. The dump will be used to update the baseline memory images maintained on the ground.

The schedule of targets for the next week is shown below and includes observations of IGR J17091-3624, which are follow-ups to a Target of Opportunity accepted Mar 25, an observation of MAXI J0556-332, which was accepted as a Target of Opportunity on May 3, an observation of IGR J17091-3624 coordinated with NuSTAR, and an observation of Jupiter coordinated with HST.
