Operations CXO Status Report

Friday 22 October 2021 9.00am EDT

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

A real-time procedure was executed on Oct 15 to update several telescope subsystem K-constants related to the insertion and retraction of gratings in order to account for spacecraft thermal trends. Additional real-time procedures were executed on Oct 15-17 to dump OBC-A and -B memory as a follow-up to the patch. The dump will be used to update the baseline memory images maintained on the ground.

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 Aug 25 and is coordinated with VLA, and an observation of eRASSt J234403.0-352640, which is a follow-up to a Target of Opportunity accepted on May 11.
