Operations CXO Status Report

Friday 7 September 2018 9.00am EDT

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

A real-time procedure was executed on Sep 6 to perform a routine self-check of the Electrical Interface Assembly (EIA) Sequencer.

A Chandra image release was issued on Sep 6 describing a new composite image of the galaxy AM 0644-741. The image is derived from X-rays data from Chandra, combined with optical data from NASA's Hubble Space Telescope. The Chandra data reveal the presence of very bright X-ray sources, most likely binary systems powered by either a stellar-mass black hole or neutron star, in a remarkable ring. For details see: http://chandra.si.edu/photo/2018/ring/

The schedule of targets for the next week is shown below and includes an observation of TXS 2116-077, which was accepted as a Director's Discretionary Time Target of Opportunity on Aug 20 and is coordinated with Gran Telescopio Canarias, and observations of 21P/Giacobini-Zinner, which are follow up to a Target of Opportunity accepted on Aug 10.
