During the last week the observing schedule was interrupted by a high-radiation event that activated the science instrument safing sequence (SCS 107) and stopped observing at at 7:34am EDT on Mar 24. All spacecraft actions were nominal. Loads for a replanned schedule were uplinked on Mar 25. Planned observations of AGC 724821, IGR J18172-1944, EP240315A, 2MASSJ08194059+0823, 4C+62.29, NGC4261, and NGC6204 were impacted by the interruption and will be rescheduled.

Real-time procedures were executed on Mar 28 to perform a dump of the IU-A EEPROM and diagnostic memory dumps of the Command and Telemetry Unit (CTU) EEPROMs.

Chandra passed through the 26th, 27th, and 28th eclipses of the season on Mar 23, 25, and 28 respectively, with nominal power and thermal performance.

A Chandra image release was issued on Mar 27 showing the stunning echo of an 800-year-old explosion in SNR 1181. This supernova has been associated with Pa 30, a nearly circular nebula with a central star in the constellation Cassiopeia. The new composite image uses data across the electromagnetic spectrum and shows a spectacular new view of the supernova remnant. This allows us to marvel at the same object that appeared in our ancestors’ night sky more than 800 years ago. For details see: https://chandra.harvard.edu/photo/2024/snr1181/

The schedule of targets for the next week is shown below and includes an observation of ZTF19acnskyy, which was accepted as a Director's Discretionary Time Target of Opportunity on Mar 25, and an observation of EP240222a, which was accepted as a Director's Discretionary Time Target of Opportunity on Mar 26.
