Proton Events: A greater than 10 MeV proton event above the 10 PFUs threshold occurred at 23/1500Z. The current maximum of 13 PFUs occurred at 23/1535Z. The greater than 10 MeV protons are currently enhanced, but below threshold. C. Geomagnetic Activity Summary: The geomagnetic field was quiet. D. Stratwarm: Not Available E.
