Operations CXO Status Report

Friday 20 June 2003 7.30am EDT

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

Following the warm-restart of IRU-1 gyro-1 on 13 June, its current has returned from the restart value of ~100 mA to approximately the same level as prior to the warm-restart (~140 mA). This behavior is consistent with a trend towards eventual out of spec (anomalous) performance and the team is currently assessing a swap to IRU-2 in order to retain maximum operational lifetime on gyro-1. IRU-2 has continued to operate in parallel with IRU-1 and the initial calibration was completed last week without impact to operations.

A Chandra press release was issued on June 19 describing results from the Great Observatories Origins Deep Survey (GOODS) that combines observations from both Chandra and Hubble. For details see: http://chandra.harvard.edu/press/03_releases/press_061903.html.

The observing schedule for next week is shown below and includes a follow-up observation of the Target of Opportunity H1743-322.
