As expected, the ACE P3 rates have climbed.  They are now at 17,100. The GOES
Proxy drop has become slightly shallower.

 As we are presently in the RAD Zone, ACIS is not collecting fluence. I expect
 the P3 rates to continue to increase.  We exit the RAD zone tomorrow morning
 at 6:22am local. There is a Comm scheduled soon thereafter for 7:30am Local.
 The next Comm after that is 5:50pm local.


Sep 12 Email Alert
-------------------
A Radiation violation of GOES 13 P2 (4-9 MeV) has occurred indicating a
possible EPHIN P4GM value of 1/3 the threshold.
 Value:  32.30 p/cm2-s-sr-MeV
  Limit:  30.00


Sep 12 Telecon Summary
-----------------------
Telecon prior to 255:1130-1230z comm to discuss current radiation. ACE P3
rates high and projected to exceed a fluence of 2e9 prior to the afternoon
comm. Arrival of second CME predicted for ~255:1300z. Given the radiation and
available comm the decision was made to run SCS 107 to halt observing and safe
the science instruments. SCS 107 was initiated via ground command at
255:11:51:18z and ran nominally. Have a clean-up action to disable SCS 29 via
pre-approved CAP.

An initial plan for science resumption is to uplink at the 256:1150-1250z pass
and to incorporate ObsID 16511 to meet its window constraint. A discussion of
the radiation environment will be held in conjunction wit the load review.
Email announcing the time will be sent to sot_yellow_alert once the load
review time is known.
