Operations CXO Status Report

Friday 21 February 2020 9.00am EDT

During the last week the observing schedule was replanned to incorporate an observation of GRB200219A, which was accepted as a Target of Opportunity on Feb 19. Loads for the replanned schedule will be uplinked on Feb 21. A scheduled observation of SPT-CLJ2335-5434 was impacted by the replan and will be rescheduled in a future week.

A real-time procedure was executed on Feb 15 to perform a diagnostic dump of the Control Processing Electronics (CPE).

A Chandra image release was issued on Feb 20 featuring several X-ray binary stars in the Milky Way globular cluster Terzan 5, located about 19,000 light years from Earth. The most remarkable of these binaries, composed of a neutron star in a close orbit with a sun-like star, was observed switching between the behavior expected for a low-mass X-ray binary to that expected for a millisecond pulsar and back again. For more information see: https://chandra.harvard.edu/photo/2020/terzan5/

The schedule of targets for the next week is shown below and includes an observation of SN2020bvc, which is a followup to a Director's Discretionary Time Target of Opportunity accepted on Feb 12.
