Operations CXO Status Report

Monday 1 May 2000 8.30am EDT

During the last week, Chandra completed the observing schedule as planned. One real-time procedure is planned during the next week to continue testing the ACIS "squeegee mode". The test scheduled for 4:45pm on 5/1 will use the same number of CCD rows as for the 4/15 test (8 and 16), but with reduced parallel transfer times. The test is intended to verify that the energy resolution improves on-orbit in the same manner as in lab tests. The planned observations for next week are as follows.

Note that a request for a Target of Opportunity was made on 4/30 and is under assessment. If the TOO is approved, the next status report will include the schedule revisions made to accommodate the observations.

The spacecraft subsystems continued to operate nominally.
