During the last week the observing schedule was replanned to incorporate an observation of EP250207B, which was accepted as a Director's Discretionary Time Target of Opportunity on Feb 10. Observations impacted by the replan will be rescheduled in a future week.

Chandra passed through the 10th, 11th, and 12th eclipses of the season on Feb 8, 11, and 14 respectively, with nominal power and thermal performance.

Of note this week was the approval of an On-board Computer (OBC) flight software patch and ground product updates that enable the return to operations of the LETG. Operations had been suspended following the LETG insertion anomaly on Jan 11.

A Chandra image release was issued on Feb 12 showing a "bouquet" of budding young stars in a new composite image of 30 Doradus (30 Dor). Also known as the Tarantula Nebula, 30 Dor is one of the brightest and most crowded regions of star formation relatively close to Earth. This new image contains X-rays from Chandra, optical data from Hubble, infrared data from Spitzer, and radio data from ALMA. The Chandra data are the deepest X-ray image ever taken of 30 Dor, revealing thousands of X-ray sources and a diffuse X-ray glow. For details see: https://chandra.harvard.edu/photo/2025/30dor/.

A Chandra press release was issued on Feb 13 describing observations of the Phoenix cluster that have finally solved the mystery of how a massive galaxy cluster is forming stars at such a high rate. Using data from NASA's James Webb Space Telescope, Chandra X-ray Observatory and Hubble Space Telescope, as well as several ground-based observatories, researchers were able to make an accurate census of the cooling gas across the full temperature spectrum. With the discovery of intermediary warm gas within cavities tracing the very hot gas, they were able to reconcile the cooling and star-formation rates.

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