Proton Events: The greater than 10 MeV proton flux briefly reached 1070 pfu at 22/1900 UTC. The increase was the result of the arrival of the 21 Jun CME. C. Geomagnetic Activity Summary: The geomagnetic field was at quiet to severe storm levels due to effects from the arrival of multiple CMEs. D. Stratwarm: Not Available E.
