Operations CXO Status Report

Friday 22 December 2017 9.00am EST

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

Preparations are complete for the winter 2017/18 eclipse season; the season contains six eclipses and runs from Dec 22 to Jan 5. Real-time procedures were executed on Dec 21 to prepare for the first eclipse: one to activate SCS 29 and one to dump and clear the EPS glitch counters.

A Chandra press release was issued on Dec 19 describing observations of the Perseus cluster. New analysis shows that absorption of X-rays at 3.5 keV is detected when observing the region surrounding the supermassive black hole at the center of Perseus. This suggests that dark matter particles in the cluster are both absorbing and emitting X-rays at that energy. For details see: http://chandra.si.edu/press/17_releases/press_121917.html

The schedule of targets for the next two weeks is shown below and includes observations of NGC 3516 coordinated with NuSTAR, observations of 3C 111 coordinated with NuSTAR and HST, an observation of GM Aur coordinated with HST and the VLA, observations of DM Tau, which was accepted as a Director's Discretionary Time Target of Opportunity on Nov 22, an observation of MAXI J1535-571, which was accepted as a Target of Opportunity on Dec 12, and an observation of eMACSJ0324.0+2421, which was accepted as a Director's Discretionary Time Target of Opportunity on Nov 6.
