Operations CXO Status Report
Friday 29 November 2002, 7.30am EST
Last week the observing schedule was halted due to high radiation
associated with solar flare activity. The loads were halted on Nov 26
at 7:02pm EST through a ground command to execute the SI Safing SCS 107.
This ensured that the accumulated radiation dose for ACIS remained
below the allowed threshold. Loads were restarted at 10:30pm EST on
Nov 27. Observations of BR 2213-6729, SNR1987A, PSR J1016-5857, HS
1251+2636 and J132512+112329 (total 90.5 Ks) were impacted by the
event and will be rescheduled in a later load.
Of note last week was the announcement of Very Large Observing
Projects available to proposers in Cycle 5. Up to 3 million seconds
have been allocated for projects requiring 1 million seconds or
more. For details see http://asc.harvard.edu/udocs/VLP.html.
The observing schedule for next week is shown below and includes an
observation of M31 coordinated with the Hubble Space Telescope. The
load also includes the commanding to conduct an aspect camera dark
current calibration on Dec 3.
