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

Real-time procedures were executed on Oct 7 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 further real-time procedure was executed on Oct 8 to enable SCS 93 as needed for observations with HRC-S in the upcoming schedule.

Of note this week, Release 2.2 of the Chandra Source Catalog was announced. This release of the catalog expands coverage and improves astrometry. This catalog, which covers roughly 785 square degrees of sky, contains 432,713 unique X-ray sources and more than 1.4 million individual source detections identified in more than 17 thousand Chandra imaging observations released publicly from the start of 2000 to the end of 2023.

A Chandra image release was issued on Oct 8 featuring composite images of data from NASA's Chandra and Neil Gehrels Swift Observatories, along with other NASA and ESA space telescopes and ground-based facilities. These images celebrate the legacy of Swift as it approaches its final days in orbit. Swift complements the high angular resolution capability of Chandra with quick capture of rapidly-changing events in space in ultraviolet, X-ray, and gamma-ray light. The images show the Small Magellanic Cloud (one of the Milky Way’s closest galactic neighbors) and the galaxies NGC 1097, NGC 4151, and NGC 1365.
