Operations CXO Status Report

Friday 30 April 2010 9.00am EDT

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

A real-time procedure was executed on Apr 29 to update the on-board ephemeris.

A Chandra press release was issued on Apr 29 describing evidence for the existence of two mid-size black holes close to the center of the nearby starburst galaxy M82. It has been a mystery of whether black holes exist with masses in between the stellar mass and supermassive categories. Evidence suggests that these two objects avoided falling into the giant black hole at the center of M82. It is possible these intermediate-mass black holes are examples of seeds required for the growth of supermassive black holes. For details see: http://chandra.harvard.edu/press/10_releases/press_042910.html

Of note last week was the Chandra User Committee meeting held at the CXC on Apr 27-28.

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