Operations CXO Status Report

Friday 23 February 2024 9.00am EST

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

Chandra passed through the 13th, 14th, and 15th eclipses of the season on Feb 17, 20, and 23 respectively, with nominal power and thermal performance.

A Chandra press release was issued on Feb 21 describing the discovery of a giant eruption from a supermassive black hole in a cluster of galaxies. Some of the gas sent away from the black hole by the eruption eventually cooled enough to form numerous clusters of stars. Today astronomers see 19 distinct star clusters that may be connected to this event some 200 million years earlier in the cluster’s history. Researchers used NASA’s Chandra X-ray Observatory, the LOFAR radio network and other telescopes to make this discovery. For details see: https://chandra.harvard.edu/press/24_releases/press_022124.html

The schedule of targets for the next week is shown below and includes an observation of SDSS J095902.76+021906.3, which was accepted as a Target of Opportunity on Jan 30, and an observation of MCG-6-30-15 coordinated with XRISM.
