Operations CXO Status Report

Friday 7 October 2022 9.00am EDT

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

Real-time procedures were executed on Oct 5 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).

Chandra passed through the 1st, 2nd, and 3rd eclipses of the season on Sep 30, Oct 3, and 6 respectively, with nominal power and thermal performance.

A Chandra image release was issued on Oct 4 presenting new images which combine X-rays from Chandra with infrared data from early publicly-released James Webb Space Telescope images. The four objects were among the first images released by JWST after it finished its commissioning process. Chandra data generally show higher-energy phenomena (like superheated gas and the remnants of exploded stars) than Webb’s infrared view. Astronomers plan to combine data from these telescopes for many different objects in the future. For details see: https://chandra.harvard.edu/photo/2022/chandrawebb/

The schedule of targets for the next week is shown below.
