Operations CXO Status Report

Friday 3 May 2019 9.00am EDT

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

A real-time procedure was executed on Apr 26 to dump the ACIS flight software as part of End to End Ground System Verification of the Wayside Operations Control Center. Additional real-time procedures were executed on Apr 28 and May 1 to perform full-frame dark current readouts of the Aspect Camera Assembly CCD. Another real-time procedure was executed on May 1 to perform a routine self-check of the Electrical Interface Assembly (EIA) Sequencer.

The schedule of targets for the next week is shown below and includes an observation of MAXIJ1820+070, which was accepted as a Target of Opportunity on Apr 18 and is coordinated with the VLA, an observation of Proxima Centauri which was accepted as a Director's Discretionary Time Target of Opportunity on Apr 8 and is coordinated with ALMA, TESS, HST, SWIFT, and several ground-based optical observatories, an observation of PKS 1830-211, which was accepted as a Director's Discretionary Time Target of Opportunity on Apr 15, observations of Swift J184418.3-023304 and 3XMM J182855.9-095413, which were accepted as Targets of Opportunity on Mar 22, an observation of Gaia17bpi, which is a follow-up to a Target of Opportunity which was accepted on Dec 21, an observation of Swift J1728.9-3613, which is a follow-up to a Target of Opportunity on which was accepted on Feb 6, observations of DES J0420-4037 and GraL 1537-30, which were accepted as Director's Discretionary Time Targets of Opportunity on Nov 30, and an observation of SDSSJ085051, which was accepted as a Director's Discretionary Time Target of Opportunity on Apr 22.
