Operations CXO Status Report

Friday 12 February 2021 9.00am EST

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

Real-time procedures were executed during each ground contact to reset the DSN Outage Dead Man Load.

A Chandra press release was issued on Feb 8 describing the first evidence for a rare type of supernova in the Milky Way. This intriguing object lies near the center of our galaxy in a supernova remnant called Sagittarius A East. Chandra data revealed that this object may belong to a special group of Type Iax supernovas, which will help us understand the different ways that white dwarf stars can explode. For details see:

The schedule of targets for the next week is shown below and includes an observation of MAXI J1848-015, which was accepted as a Target of Opportunity on Jan 19, observations of WISEA J101022.95+141301.0 coordinated with VLA, and an observation of V404 Cygni coordinated with VLA.
