Operations CXO Status Report

Friday 10 February 2017 9.00am EST

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

A Chandra press release was issued on Feb 6 describing the growth of the black hole XJ1500+0154. The X-ray observations from Chandra, Swift and XMM-Newton found evidence for a "tidal disruption event" (TDE). The extraordinary long bright phase of this event spanning over ten years means that among observed TDEs this was either the most massive star ever to be completely torn apart during one of these events, or the first where a smaller star was completely torn apart. For details see:

The schedule of targets for the next week is shown below and includes observations of M87 coordinated with NuStar, Markarian 1018 which was accepted as a Target of Opportunity Dec 19 and is coordinated with HST, and CSS161010 which was accepted as a Director's Discretionary Time Target of Opportunity on Dec 21.
