B. Proton Events
The greater than 10 MeV proton flux remained
mildly enhanced, ~1.5 pfu, and was trending towards background
levels. A pair of slight enhancements below 3pfu as a CME passed
Earth.
C. Geomagnetic Activity Summary
The geomagnetic field was quiet to
unsettled, with an isolated active period.
