Operations CXO Status Report

Friday 3 December 2021 9.00am EST

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

Chandra passed through the twelfth, thirteenth, and fourteenth eclipses of the season on Nov 27, Nov 30, and Dec 03 respectively, with nominal power and thermal performance.

Real-time procedures were executed on Dec 1 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).

Of note this week, summary X-ray properties from the Chandra Source Catalog (CSC) version 2.0.1, which provides information on 317,167 unique X-ray sources detected with Chandra during its first 15 years of operations, have been integrated into the NASA/IPAC Extragalactic Database (NED). This makes the benefits of NED queries -- positional crossmatch and cross-identification with existing sources, homogeneous multi-wavelength photometry and spectral energy distribution, redshift, classification, distance and other source properties -- available for the exploration of CSC sources. For more details, see

The schedule of targets for the next week is shown below and includes observations of GW170817 coordinated with VLA.
