During the last week Chandra completed the observing schedule as planned. Real-time procedures were executed on Sep 3 to perform a routine self-check of the Electrical Interface Assembly (EIA) Sequencer and to perform a diagnostic dump of the Control Processing Electronics (CPE). An additional real-time procedure was executed on Sep 9 to perform an annual check-out of A-side MUPS thrusters, which are selected for use when Chandra is in its safe-mode configuration. Thrusters A2, A3, and A4 were fired. Thrusters performed nominally. Thruster A1 was not fired due to the expected limited life remaining on it. The schedule of targets for the next week is shown below and includes an observation of MAXI J1848-015, which was accepted as a Target of Opportunity on Aug 25 and is coordinated with NRAO VLA. |

Use of the gratings is suspended pending a detailed review of the LETG insert anomaly. All other spacecraft subsystems continued to support nominal operations.
