Operations CXO Status Report

Friday 22 June 2007 9.00am EDT

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

A real-time procedure was completed on Jun 15 to update the on-board Ephemeris.

A real-time procedure was performed on Jun 22 to execute SCS 29 in preparation for the first eclipse of the 2007 summer season. This eclipse season consists of 8 eclipses between Jun 24 and Jul 12 and ranging from 25 to 68 minutes in duration.

Of note during the last week was the Cycle 9 Peer Review held in Boston, Jun 19-22. The results from the review are expected to be released on Jul 13.

A Chandra image release was issued on May 20 of the bright and unstable star Eta Carinae. The composite X-ray and optical image shows shows the X-ray emission produced as material thrown off Eta Carinae rams into nearby gas and dust, heating gas to temperatures in excess of a million degrees.

The schedule of targets for the next week is shown below and includes an observation of VB10 coordinated with the VLA and ground NOAO ground-based telescopes.
