Operations CXO Status Report
Friday 10 Oct 2003, 11.30am EDT
During the last week Chandra completed the observing schedule
as
planned.
The HRC team is actively investigating the cause for the HRC -Y
shutter anomaly and have traced its origin to a limited number of
components in the motor control electronics. Since some of these
components are used in the operation of the HRC door, the team has
recommended that once the door is opened for the next HRC observation
it remain open at least until those components are exonerated. While
the HRC door will not be moved so that it blocks low-energy protons
from reaching the detectors during radiation zone passages, early
mission experience indicates that there is minimal-to-no risk of
degradation to the HRC from radiation with the door in this open
position.
The observing schedule for next week is shown below and includes
an
observation of EXO 0748-676 coordinated with RXTE.
