Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field ranged from quiet to active levels. Solar wind speeds increased up to around 600 km/s at 02/2300 UTC, but dropped down to 500-550 km/s from 0100-1900 UTC. However, there appears to be another solar wind speed increase in progress at this time. The greater than 2 MeV fluence at geosynchronous orbit reached moderate levels today. D. Stratwarm: None E.
