B. Proton Events
The greater than 10 MeV proton event that began at 05/0030Z, reached a maximum of 844 pfu at 08/0035Z, crossed below the 100 pfu threshold at 08/0620Z. Protons are currently around the 10 pfu threshold.
C. Geomagnetic Activity Summary
The geomagnetic field was at active to severe storm levels due to CME effects.
