Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field has been at active to minor storm levels. Portions of the high speed stream from a departing coronal hole remain, keeping the solar wind speeds above 420 km/s. The interplanetary magnetic field continues to be oriented southward. D. Stratwarm: None E.
