An X-class flare on Nov 4 triggered a radiation violation on Nov 5.
A Radiation violation of P3 (130Kev) has been observed by ACE. There have been
several M class flares in the past 12 hours (since start of day 313).


Nov 5, 2001 Shift Report
-------------------------

SCS 107 ran due to a RADMON trip on day 308 (Sunday, Nov 4) at 17:37:06 UT. 
At the trip time we were running OCT2801A and observing 'PSR0628-28' (obsid 2010).
The trip was noticed during the 1830-1930 pass. The safing sequence ran nominally.

A maneuver load (NOV0501C) has been built and uplinked to the S/C. The S/C will
execute the maneuver today (day 309) at 2200UT. The maneuver is needed to avoid
an earth ocultation. The maneuver to attitude is good for many (12) days. 

The radiation conditions now are severe and preclude immediate return to science. 
ACE protons are at 20,000 flux and rising. GOES EPHIN predictors indicate 
HE proton levels above EPHIN trip points. Additional solar activity is predicted. 

It was decided in the radiation meeting (after 9am) to build an intercept load
starting at obsid 2172 (see below). An issue with this is that the last valid
(not in belts) EPHIN data would be from the COMM at 311:1650, well before the 
observation start at 312:0741. MP was asked to try for COMM after rad exit 
on 312:0418 and prior to start of observation. 

From current GOES proton rates, we would estimate P4GM and P41GM are
factors of 10 to 30 above the EPHIN RADMON trigger levels, whereas we
will require them to be no more than 1/3 the trigger level before
resuming the load. Observed rates are 20 to 50 times above trigger levels.

We are working to a replan which would resume with OBSID 1624 when we
exit perigee at about 312:09, but in view of the strength of the current
storm, we are pessimistic that it will abate by then. Additional comm
has been obtained so that we can check the EPHIN rates after perigee
passage #311, before committing to activate the loads.
