Operations CXO Status Report

Friday 17 December 2010 9.00am EST

During the last week Chandra completed the observing schedule as planned.

Two real-time procedures were completed on Dec 16; the first to update the on-board ephemeris and the second to uplink an update to the on-board gyro scale-factor and alignment matrix.

A Chandra image release was issued on Dec 14 describing observations of SNR 0509-67.5, a supernova remnant located in the Large Magellanic Cloud, a satellite galaxy to the Milky Way about 160,000 light years away. Optical data of SNR 0509-67.5 and its accompanying star field, taken with the Hubble Space Telescope, are composited with X-ray energies from the Chandra X-ray Observatory. The result shows heated material from the X-ray data surrounded by an optical shell which shows the ambient gas being shocked by the expanding blast wave from the supernova. For details see: http://chandra.harvard.edu/photo/2010/snr0509/

Of note this week was the release on Dec 15 of the Cycle 13 Call for Proposals. The proposal submission deadline is 15 March 2011. In conjunction with the call was the release of the CIAO 4.3 analysis software system together with CALDB 4.4.1. The release includes the implementation of a sub-pixel positioning algorithm for ACIS events along with many other tool enhancements and improvements.

The schedule of targets for the next week is shown below.
