Operations CXO Status Report

Friday 9 February 2007 7.30am EDT

During the last week the observing schedule was replanned to include a 20 Ks observation of the X-ray pulsar 4U 0142+61 TOO following the detection of a large burst. The source was accepted as a fast turn-around Target Of Opportunity (TOO) on 7 January and loads were replanned and uplinked on 9 January. The observation was accommodated by shortening an observation of G1.9+0.3.

Real-time procedures were executed on February 8 to perform a routine self-check of the Electrical Interface Assembly (EIA) sequencer and to update the on-board ephemeris.

The schedule of targets for next week is shown below and includes an observation of M87 coordinated with HST.
