B. Proton Events
The greater than 10 MeV proton event that began on 08/0215Z reached a peak flux of 1040 pfu at 10/1105Z. The greater than 100 MeV proton event that began at 08/0405Z reached a peak flux of 7 pfu at 09/1920Z.
C. Geomagnetic Activity Summary
The geomagnetic field ranged from quiet to minor storm levels. Southward Bz and continued transient flow are responsible for the elevated conditions.
