Operations CXO Status Report 20 September 2002

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

A real-time procedure was completed on Sept 16 to update the on-board
ephemeris. Of note last week was the release to operations of OFLS
9.4. The ground system software update provides additional control
over star catalog commanding when generating command loads.

Two press releases were issued last week. The first on Sept 13 reports
the discovery of 6 times the expected number of galactic-scale black
holes in an observation of a galaxy cluster. The second on Sept 19
was issued as a NASA HQ Space Science Update and describes a
remarkable series of images of the Crab nebula combined to make a
‘movie’. The sequence shows bright wisps emanating from the inner
ring around the pulsar. For detail see:

The observing schedule for next week is shown below and includes an
observation of 4U 1746-37 coordinated with RXTE.
