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

Chandra passed through a penumbral lunar eclipse on Aug 23 with nominal power and thermal performance.

Real-time procedures were executed on Aug 23 to disable SCS-29 and to dump and clear the EPS glitch counters as post-eclipse season actions.

Chandra press and image releases were issued on Aug 28 describing observations of the Cassiopeia A supernova remnant (Cas A), the remnant of a massive star about 11,000 light years from Earth. A new Chandra study reveals that, hours before it exploded, the star’s interior violently rearranged itself. As massive stars age, increasingly heavy elements form in their interiors by nuclear reactions, creating onion-like layers of different elements. New research reveals the major changes in Cas A's progenitor star just hours before it exploded: part of an inner layer with large amounts of silicon traveled outwards and broke into a neighboring layer with lots of neon, which was in turn forced downward. Traces of these outward silicon flows and inward neon flows can still be observed in the Cas A supernova remnant. For details, see https://chandra.harvard.edu/press/25_releases/press_082825.html

The schedule of targets for the next week is shown below and includes observations of AT2025ulz, which was accepted as a Target of Opportunity on Aug 21, and an observation of GRB250702B, which was accepted as a Director's Discretionary Time Target of Opportunity on Aug 15.
