Operations CXO Status Report

Friday 3 November 2006 8.00am EDT

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

A real-time procedure was completed on 31 Oct to perform a dump of OBC-A memory. The dump confirmed that that the cause of a fixed overflow error recorded on 15 Oct was the benign roll-over of the ground command counter, cmd_accept_count. A second real-time procedure was conducted on 1 Nov to perform a routine self-check of the Electrical Interface Assembly (EIA) Sequencer.

A Chandra image release was issued on 2 Nov of a composite Chandra/Hubble/VLA image of the galaxy cluster MS0735.6+7421. For details see: image http://chandra.harvard.edu/photo/2006/ms0735/
