B. Proton Events
The greater than 100 MeV event that began at 13/1810Z, reached a peak value of 1 pfu at 13/1905Z, and ended at 13/2255Z The 10 MeV proton event greater than 100 pfu (S2-Moderate) event began at 13/1855Z, reached a peak value of 469 pfu at 13/2045Z, and dropped below 100 pfu into S1-Minor threshold at 14/0955Z. The S1-Minor storming level remains in progress as of the close of this period.
C. Geomagnetic Activity Summary
Field activity was mostly quiet to unsettled in the mid latitudes with periods of active levels at high latitudes.
