Operations CXO Status Report

Friday 29 March 2013 9.00am EDT

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

Chandra passed through the fourteenth and final eclipse of the season on Mar 24, with nominal power and thermal performance. Real-time procedures were executed on Mar 24 to set the short eclipse flag to "false", to disable SCS-29, and to dump and clear the EPS glitch counters as post-eclipse season actions.

A flight software patch was uplinked on Mar 28 to update the on-board gyro calibration misalignment matrix. Real-time procedures were executed on Mar 28 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 an observation of SN 2013ai, which was accepted as a Target of Opportunity on Mar 20.
