B. Proton Events
C. Geomagnetic Activity Summary
The geomagnetic field was at quiet to unsettled levels with an isolated active period at middle and high latitudes between 22/1800 and 2100 UTC. The NASA/ACE instrument detected a weak shock passage at approximately 22/1300 UTC. The Bz component of the interplanetary magnetic field has been predominantly north since transient onset. The greater than 2 MeV electron flux at geosynchronous orbit reached moderate levels today.
