Operations CXO Status Report

Friday 17 May 2024 9.00am EDT

During the last week the observing schedule was interrupted due to high radiation associated with solar activity. The loads were halted at 11:37am EDT on May 10 through a ground command to execute the SI Safing SCS 107. All spacecraft actions were nominal. Real-time procedures were executed on May 10 to disable SCS-29, which was enabled during the safing sequence, and to change the ObsID. Loads for a replanned schedule were uplinked on May 13. Planned observations that were impacted by the interruption will be rescheduled.

A real-time procedure was executed on May 14 to perform a diagnostic dump of the Control Processing Electronics (CPE).

The schedule of targets for the next week is shown below and includes an observation of Gaia BH3, which was accepted as a Director's Discretionary Time Target of Opportunity on Apr 21, and an observation of Ass Cha T 2-54 coordinated with HST/JWST.
