Operations CXO Status Report

Friday 6 November 2020 9.00am EST

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

Real-time procedures were executed on Oct 30 and Oct 31 to dump OBC-A and -B memory as a follow-up to the flight software patches executed on Oct 29. The dump will be used to update the baseline memory image maintained on the ground. Real-time procedures were also executed on Nov 4 to perform a routine self-check of the Electrical Interface Assembly (EIA) Sequencer and to perform a diagnostic dump of the Control Processing Electronics (CPE).

Additional real-time procedures were executed during each ground contact to reset the DSN Outage Dead Man Load.

The schedule of targets for the next week is shown below and include observations of SN2020tcw, which was accepted as a Target of Opportunity on Oct 16, and an observation of AT2020xnd, which was accepted as a Target of Opportunity on Oct 26 and is coordinated with NuSTAR.
