The high proton counts occurred following passage of an interplanetary shock
wave due to a halo coronal mass ejection associated with two X-class solar
flares on 6 June.

From real-time data at AOS (160:1120) it was determined that the
RADMON safing action had taken place and SCS 107 had been run to
safe the instruments. Indications of this were:
     - S/C downlink telem had to be commanded on from ground
     - SIM was at HRC-S posn (-99615)
     - ACIS science was idle
     - SCS 107 was Disabled and at step 107

The only issue with SCS107 was that the HETG had NOT retracted
as expected. This was due to the fact that SCS 107 has not yet 
been patched to use MCE-B.

The fact that the HETG is in is not a problem for now although 
the reason for its not retracting must be understood prior to
starting another load.

Both ACIS and HRC have been safed correctly per procedure.

HRC will have to run CAP 613 again at some point to move the door back
to the 10,000 step open posn.

   This was our second attempt today to start the CTI measurement
after this large solar event.  At the earlier pass (160:20:45), the 
EPHIN P4 rate was fluctuating between 1600-1850 cts/sample. I decided 
that was too high to start the CTI measurement.  At the beginning of 
this pass, the EPHIN P4 rate was 667 cts/sample.  ACE rates have shown
a slow, steady decline from 80,000 to 50,000 particles/cm2-s-ster-MeV.
