Operations CXO Status Report

Friday 10 July 2015 9.00am EDT

During the last week the observing schedule was replanned to incorporate an observation of V404Cyg, which was accepted as a Director's Discretionary Time Target of Opportunity on Jul 2. Loads for the replanned schedule were uplinked on Jul 10. Scheduled observations of UDS and Cl1813-178 were impacted by the replan and will be will be rescheduled in a future week.

Preparations were completed for the summer 2015 eclipse season; the season contains eleven eclipses and runs from Jul 7 to Aug 3. Real-time procedures were executed on Jul 6 to prepare for the first eclipse: one to activate SCS 29 and one to dump and clear the EPS glitch counters. Chandra passed through the first eclipse of the season on Jul 7, with nominal power and thermal performance.

A Chandra press release was issued on Jul 9 describing the discovery of a supermassive black hole in the early universe that grew much more quickly than its host galaxy. This is contrary to previous understanding of the development of galaxies where the growth of black holes and formation of stars go hand-in-hand. For details see: http://chandra.harvard.edu/press/15_releases/press_070915.html

The schedule of targets for the next two weeks is shown below, and includes observations of V404Cyg, a peer-reviewed Target of Opportunity approved on Jul 2 and coordinated with VLA, an observation of MWC656 coordinated with VLA, an observation of PDS 456 coordinated with NuSTAR, and an observation of 3C 273 coordinated with XMM, Suzaku, and NuStar:
