Proton Events: A greater than 10 MeV proton event began at 07/0500Z and has reached a peak of 1740 PFU at 07/2305Z. A greater than 100 MeV proton event also occurred, beginning at 07/0405Z and reaching an apparent maximum of 69 PFU at 07/1540Z. Both of these events continue in progress at the time of this report. C. Geomagnetic Activity Summary: The geomagnetic field has been at unsettled to severe storm levels for the past 24 hours. D. Stratwarm: Not Available E.
