Operations CXO Status Report

Friday 30 August 2019 9.00am EDT

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

Real-time procedures were executed on Aug 19 and Aug 28 to perform full-frame dark current readouts of the Aspect Camera Assembly CCD.

A Chandra image release was issued on Aug 26 showing results from Chandra observations of the supernova remnant Casseopeia A. The shock-heated debris from this explosion of a massive star glows brightly at multiple wavelengths, including X-rays. From Chandra's iconic "first light" image released Aug 26, 1999 to the present, Chandra has repeatedly returned to study this object, in the process revealing a great deal about the physics of the explosion, the elemental composition of debris, and the remnant central neutron star. The successive observations span a sufficiently long interval to reveal complex gas motions. For more information see: http://chandra.harvard.edu/photo/2019/firstlight/

The schedule of targets for the next week is shown below and includes an observation of V1369Cen, which was accepted as a Director's Discretionary Time Target of Opportunity on Jul 29, and an observation of V3890Sgr, which was accepted as a Director's Discretionary Time Target of Opportunity on Aug 29.
