Operations CXO Status Report

Friday 17 December 2004 7.00am EST

During the last week the observing schedule was replanned to include an observation of BL 0502+675 that was approved as a fast turn-around Target Of Opportunity (TOO) on Dec 13. Loads were replanned and uplinked late on Dec 13 for observing on Dec 14. Observation of SDSS J031950.54-00, cl0318-0302, SDS 1321+0038, MKW8 and E0102-72 were impacted by the TOO and will be rescheduled for a later load.

A real time procedure was completed on Dec 14 to uplink the final flight software patch to allow the HRC event and anti-coincidence shield rates to be used by the radiation monitor process to monitor high radiation events. The patch is designed for use within the radmon process, providing a backup to the EPHIN detector. A second realtime procedure was performed on Dec 14 to measure the performance of the ACIS focal plane temperature set point.

A Chandra press release was issued on Dec 14 describing observations of the supernova remnant 3C58 that show the central pulsar is surrounded by a bright torus of X-ray emission with bi-directional jets extending from the center. For details see:

The schedule of targets for the next week is shown below and includes an observation of NGC 5408 ULX coordinated with the VLA.
