Operations CXO Status Report

Friday 9 August 2002 2.15pm EDT

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

Observations included a target of opportunity, GX 1+4, coordinated with RXTE; an observation of Uranus; a simultaneous ACIS/HRC observation in which HRC-I observed RXJ1856.5-3754 while ACIS observed the background; and two observations coordinated with ground telescopes.

Chandra passed through eclipses 1 and 2 of the 2002 Fall season on August 7 and 9 with nominal power and thermal performance.

A routine real-time procedure was completed on August 7 to update the ephemeris.

A press release was issued on August 8 featuring a composite X-ray, radio and optical image of Centaurus A (http://chandra.harvard.edu/press/02_releases/press_080702.html) that is believed to provide evidence of a giant eruption in the center of the galaxy about 10 million years ago.

The observing schedule for next week is shown below.
