Operations CXO Status Report

Friday 5 February 2021 9.00am EST

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

A real-time procedure was executed on Feb 1 to swap the prime solid-state recorder (SSR) from the B-side to the A-side. This swap concludes a six-month interval of health and trending data collection on SSR-B. Real-time procedures were also executed on Feb 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).

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 includes an observation of NGC454E coordinated with NuSTAR.
