Operations CXO Status Report

Friday 12 January 2007 11.00 am EDT

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

Chandra passed through the 4th, 5th and final 6th eclipse of the 2007 Winter season on Jan 6, 9 and 11 respectively. Telemetry indicated nominal power and thermal performance in all cases.

An Aspect Camera dark current calibration was performed from the on-board loads on Jan 5. Assessment of the data indicated an expected rate of increase in warm pixels.

Chandra press releases were issued on Jan 4 and Jan 10 in conjunction with the AAS meeting in Seattle. The Jan 4 release described Chandra data that provide evidence for a possible new class of supernova and the Jan 10 release discussed the detection of a light echo from Sgr A*, the supermassive black hole at the center of our galaxy. For details see:

The schedule of targets for next week is shown below and includes includes an observation of 3C273 coordinated with Spitzer.
