Proton Events: A slight enhancement of the 10 MeV protons is currently in effect due the long duration M1 event around 15/0700 UTC. C. Geomagnetic Activity Summary: The geomagnetic field has been at predominantly quiet levels for the past 24 hours with an isolated minor storm period observed at high latitudes. D.
