Operations CXO Status Report
Friday 18 July 2003, 7.00am EDT
During the last week Chandra completed the observing schedule as
planned.
The first Aspect Camera dark current calibration following the
lowering of the CCD temperature from -10 to -15 deg C was conducted on
July 14. An Initial analysis of the data indicates a reduction in the
number of warm pixels by 50-60%, as expected.
During the last week the IRU-1 gyro-1 current remained near a base
level of 150 mA with some noisy periods. Products and procedures are
on track for the planned swap to IRU-2 scheduled for 7.30am EDT on
July 19. The swap is planned during a perigee passage and is not
expected to impact science operations.
The observing schedule for next week is shown below and includes an
observation of Eta Carina coordinated with RXTE.
