Operations CXO Status Report

Friday 4 February 2022 9.00am EST

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

A real-time procedure was executed on Jan 31 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. Additional real-time procedures were executed on Feb 2 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).

A Chandra image release was issued on Feb 2 presenting a new gallery of images combining X-ray data from Chandra with data from other telescopes. The objects range from a supernova remnant within the Milky Way to a galaxy cluster millions of light years away. This is a demonstration of how new telescopes like JWST and IXPE will work with other observatories to explore the Universe. For details see: https://chandra.harvard.edu/photo/2022/archives/

The schedule of targets for the next week is shown below and includes an observation of GRB 220101A, which was accepted as a Target of Opportunity on Jan 21 and is coordinated with HST.
