Operations CXO Status Report

Friday 22 September 2023 9.00am EDT

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

Chandra passed through the 6th and 7th eclipses of the season on Sep 17 and 20 respectively, with nominal power and thermal performance.

Real-time procedures were executed on Sep 20 to update the ACIS Flight Software to version 60 (Standard H, Optional J) and to update the txings parameters to optimized values appropriate for the current state of the solar cycle. These actions will improve the robustness of ACIS operations.

Of note, the annual symposium of the NASA Hubble Fellowship Program will take place in Cambridge Sep 18-22. There will be over 60 science talks across all areas of astrophysics. For more information see:

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