Operations CXO Status Report

Friday 16 March 2007 9.00am EDT

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

An aspect camera dark current calibration was performed from the on-board loads on Mar 10. Assessment of the data indicated an expected rate of increase in warm pixels.

A realtime procedure was completed on Mar 14 to update the on-board Ephemeris.

Of note last week was the Chandra Cycle 9 proposal deadline at 6pm EDT on March 15. In excess of 660 GO proposals were received and the submission process proceeded smoothly.

Preparations are complete for a 36 minute duration lunar eclipse that will begin at 10:22 am on Mar 18. Additional power loads will be applied prior to the eclipse to ensure the bus voltage remains below maximum levels when the solar arrays are reilluminated following eclipse exit (required since the arrays are more efficient when cold).

A Chandra image release was issued on 12 March of a wide-fied panorama of a region in the the Bootes constellation. The survey is the largest contiguous field observed by Chandra, taken over 9.3 square degrees with 126 exposures of 5,000 seconds each. The data reveal more than a thousand supermassive black holes in the centers of galaxies, some up to several billion times more massive than the sun. For details see:

The schedule of targets for next week is shown below.
