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

Real-time procedures were executed on Mar 2 to perform a routine self-check of the Electrical Interface Assembly (EIA) Sequencer and to perform a diagnostic dump of the Control Processing Electronics (CPE).

Chandra press and image releases were issued on Feb 22 describing Observations of GW170817, a merger of two neutron stars and the first object detected in both gravitational waves and electromagnetic radiation. Chandra is the only observatory still able to detect light from this extraordinary cosmic collision more than four years after the original event. The most recent observations show the X-ray flux as steady, indicating a need for a new source of X-rays. One explanation for this new source of X-rays is that the expanding debris from the merger has generated a shock, while an alternative explanation is that the X-rays come from material falling towards a black hole that formed after the neutron stars merged.

The schedule of targets for the next week is shown below and includes observations of SDSS J143016.05+230344.4, which is a follow-up to a Director's Discretionary Time Target of Opportunity accepted on Feb 7, an observation of Swift J170800-402551.8, which was accepted as a Target of Opportunity on Feb 2, an observation of Swift J182404.3-1358, which was accepted as a Target of Opportunity on Feb 2, and observations of AT 2022cmc, which was accepted as a Target of Opportunity on Feb 23.
