Operations CXO Status Report

Friday 17 January 2014 9.00am EST

During the last week the radiation environment recovered enough following the high-radiation event of Jan 7 to resume operations. A replanned schedule for resuming science observations was uplinked on Jan 10 with 242.6ks of science loss.

The replanned schedule is shown below and includes an observation of XSS J12270-4859, which was accepted as a Director's Discretionary Time TOO on Dec 16 and had been impacted by the schedule interruption. Other impacted observations will be rescheduled in future weeks.

Since resumption Chandra has completed the observing schedule as planned.

A Chandra press release was issued on Jan 13 as a NASA press release describing observations of PSR B1509-58 and the COSMOS field by NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR. Combining NuSTAR's higher-energy X-ray images with Chandra data provides a unique view of these well-studied objects. For details see: http://chandra.si.edu/press/14_releases/press_011314.html

The schedule of targets for the next week is shown below
