NASA Chandra Operations CXO Status Report Friday 7 Nov 2003

The observing schedule was severely impacted last week due to the
continued exceptionally high radiation levels. Loads were resumed
at 10:17am EST on Nov 1 following the autonomous execution of SCS
107 on Oct 28 but were halted once more at 4:38pm EST on Nov 2. A
total of 50.1Ks of science data were taken and science has not be
resumed since due to continued high radiation levels. Loads are planned
to resume early morning Nov 8, space weather permitting.

During the week, a number of real-time procedures were completed
associated with the SCS 107 execution and maneuver loads required
for attitude and momentum management. In addition, ACIS required
a warm-boot following a watchdog timer reboot on Nov 2 caused by
the execution of SCS 107 during an ACIS commanding sequence. The
procedure completed nominally and ACIS is now properly configured
to resume science.

All spacecraft subsystems continued to operate nominally.
