Operations CXO Status Report
Friday 3 January 2003, 8.00am EST
I am happy to wish everyone a Happy New Year for 2003 from the Chandra
team, but greatly saddened to report the passing on December 25 of our
friend and colleague Leon Van Speybroeck. Leon was diagnosed with
malignant melanoma after only a short illness, and his passing has
come has a great shock to us all. He will be missed as a giant of
X-ray astronomy, an insightful scientist with extraordinary
engineering judgement and skill in optics design, and as a modest,
charming and thoughtful friend and colleague.
During the last two weeks the observing schedule was replanned to
include an observation of U Gem that was accepted as a 3 day
turn-around Target Of Opportunity (TOO) on 21 December. The schedule
was replanned to include two grating observations of the
TOO. Observations of NGC 1265 and MAC SJ2228.5+2036 were impacted and
will be rescheduled in a later load.
Over the last week, three new high temperatures were recorded, for the
Electron Proton Helium INstrument (EPHIN), the EPHIN I/O (EIO), and
the Fine Sun Sensor (FSS). The engineering team has been monitoring
these and several other systems due to a generally increasing thermal
trend. No immediate operational changes are required, however these
and other thermal trends are under active study.
Preparations are complete for the Jan 5-9 American Astronomical
Society (AAS) meeting in Seattle and include a Chandra press release.
The observing schedule for next week is shown below.
