Operations CXO Status Report
Friday 11/10/00 7.30am EST
Last week the observing schedule was interrupted following a high
radiation event at 6:26pm EST on Sept 8 that stopped the daily load
and activated the science instrument safing sequence (SCS 107). All
actions were nominal and assessment of the dump data confirmed that
the trigger was due to high proton counts in the EPHIN P4GM channel
exceeding the pre-defined threshold of 300 counts/cm^2/s/sr.
Observations will be resumed once the radiation falls to an acceptable
level and impacted observations will be rescheduled.
A routine check of the CPE Warm Start Count was completed on 6 Nov and
showed the value remained at 1.
A milestone was passed on November 1 - the official transition from
observing cycle 1 to cycle 2 targets. November 1 was also the cut-off
date for Cycle 1 peer reviewed Targets Of Opportunity. A small number
of Cycle 1 targets have been scheduled for December and January due to
their observing constraints.
