Operations CXO Status Report

Friday 23 November 2012 9.00am EST

During the last week the Chandra observing schedule was replanned to incorporate an observation of MLS121106:014420+082311, which was accepted as a Director's Discretionary Time TOO on Nov 19. A planned observation of NGC 660 was replaced by the TOO and will be rescheduled in a future week.

A real-time procedure was executed on Nov 19 to uplink a flight software patch that updates the duration of the large move for LETG and HETG retractions. This update is to prevent driving either grating into the bumper before the end of the large move. Additional real-time procedures were executed on Nov 19-20 to dump OBC-A memory as a follow-up to the gratings large-move duration 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 Swift-J1644+57, which was accepted as a Director's Discretionary Time TOO on Nov 1, and an observation of the Crab Pulsar coordinated with HST.
