SUMMARY _______ Executed CAP 851 to perform an ACIS-I CTI measurement. The radiation environment was well below the 1/3 trigger levels as indicated in the CAP Data looked nominal; everything went according to plan. Radmon was enabled during the CAP and the OBSID was changed to 62847. ACE and GOES rates of interest are all showing a decline at this time. ACE EPAM P3 is currently around 36,000, down from ~80,000 earlier this afternoon. EPHIN P4GM is reading at about 5, well below the trigger level of 300. ACE EPAM P3 rates will be re-evaluated during the 4:30am EDT COMM; if they are at 20,000 and rising, a page will be sent to sot_red_alert to discuss impact on the start of MAY3103. If the ACE EPAM P3 rates are at 20,000 and holding steady, or declining, a page will not be sent and the onboard loads will run uninterrupted with a scheduled StartSci for OBSID 4176 occuring at 151:13:04.
