B. Proton Events
C. Geomagnetic Activity Summary
The geomagnetic field was at predominantly active to minor storm levels. High speed solar wind speeds along with embedded transient activity are believed to be responsible for the elevated conditions. The greater than 2 MeV electron fluxes at geosynchronous orbit reached high levels again today.
