Operations CXO Status Report

Friday 9 July 2010 9.00am EDT

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

A real-time procedure was executed on Jul 7 to perform a routine self-check of the Electrical Interface Assembly (EIA) Sequencer. A second real-time procedure was executed on Jul 8 to update the on-board ephemeris.

A Chandra press release was issued on Jul 7 describing observations of a newly discovered microquasar in the nearby galaxy NGC 7793. In a microquasar, a stellar-mass black hole is being fed by a companion star. The black hole in the microquasar is generating two powerful jets, which are blowing outward and creating huge bubbles of hot gas. For details see: http://chandra.harvard.edu/press/10_releases/press_070710.html

The schedule of targets for the next week is shown below and includes an observation of GX 9+9 coordinated with RXTE and the VLA and an observation of TOO_XTEJ1752-223 coordinated with the VLA.
