Operations CXO Status Report

Friday 6 May 2022 9.00am EDT

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

Chandra passed through the 7th, 8th, and 9th eclipses of the season on Apr 30, May 3, and 5 respectively, with nominal power and thermal performance.

Real-time procedures were executed on May 4 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 May 4 with two new sonifications of well-known black holes have been released for NASA's Black Hole Week. The Perseus galaxy cluster was made famous because of sound waves detected around its black hole by Chandra in 2003. Scanning like a radar around the image, the data have been resynthesized and scaled up by 57 and 58 octaves into the human hearing range. For M87, listeners can hear representations of three different wavelengths of light - X-ray, optical and radio - around this giant black hole. https://chandra.harvard.edu/photo/2022/sonify5/

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