Operations CXO Status Report

Friday 1 February 2002 11.30am EST

During the last week the observing schedule was replanned to include an observation of the Gamma-ray Burster GRB020127 that was accepted as a Target Of Opportunity (TOO) on 29 Jan following its detection in outburst.

Preparations for the spring 2002 Earth eclipse season were completed and Chandra passed through the first eclipse with nominal power and thermal performance. The season will extend from 31 Jan to Feb 24 with 3 short eclipses ranging in duration from 19 to 35 minutes and 7 medium eclipses ranging from 41 to 56 minutes. A real-time procedure is planned to clear a glitch counter that incremented due to a known timing condition during eclipse exit.

Of note last week was the Chandra User Committee meeting held at the CXC on Jan 31 and Feb 1.

The observing schedule starting with the TOO GRB020127 and showing the targets for next week is shown below. The schedule includes an observation of M31 coordinated with HST.
