Operations CXO Status Report

Friday 9 September 2022 9.00am EDT

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

Real-time procedures were executed on Sep 7 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).

Another real-time procedure was executed on Sep 8 to uplink a flight software patch to update several Telescope subsystem K-Constants to prevent grating insertion/retraction movement failures.

The schedule of targets for the next week is shown below.
