B. Proton Events
The greater than 10 MeV proton flux values observed a slight enhancement that was likely associated with the M5 flare from Region 2673, but remained below alert thresholds.
C. Geomagnetic Activity Summary
The geomagnetic field was at quiet to unsettled levels with an isolated active periods, likely associated with sustained -Bz.
