B. Proton Events
C. Geomagnetic Activity Summary
The geomagnetic field was at quiet to active levels. NASA/ACE depicted a modest increase in the solar wind speed beginning at approximately 20/1000 UTC. The Bz component of the interplanetary magnetic field made a sharp southward movement just prior to 20/1600 UTC which brought about the onset of active conditions at all latitudes.
