Operations CXO Status Report

Friday 5 February 2010 9.00am EDT

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

A real-time procedure was executed on Feb 3 to perform a routine self-check of the Electrical Interface Assembly (EIA) Sequencer.

A Chandra press release was issued on Feb 3 describing an observation that shows the first clear evidence of a binary quasar within a pair of actively merging galaxies. The Chandra image of SDSS J1254+0846 shows a pair of quasars, located about 4.6 billion light years away, that are separated on the sky by only about 70 thousand light years. An optical image from the Baade-Magellan telescope in Chile shows tidal tails (gravitational-stripped streamers of stars and gas) fanning out from the two colliding galaxies. For details see: http://chandra.harvard.edu/press/10_releases/press_020310.html

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