Operations CXO Status Report 4 Jan 2002

Happy New Year from the Chandra Team!

During the last two weeks the observing schedule was interrupted once following a high radiation event at 1:30am EST on Dec 26 that stopped the daily load and activated the science instrument safing sequence (SCS 107). All actions were nominal and radiation levels dropped sufficiently to allow the loads to be restarted at 6pm on Dec 27. Observations of Beta Ceti, G78.2+2.1, CYG X-1, A168 were impacted by the event and will be rescheduled in a later load.

Preparations are complete for the Jan 6-10 American Astronomical Society (AAS) meeting in Washington DC, where two Chandra press releases are planned.

The schedule of observations for the coming week are shown below and include an observation of XTE J1118+480 coordinated with HST.
