Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 1820 1913 1933 0930 S07E47 M2.0 1n 85 2600 B. Proton Events: The greater than 10 MeV proton event that began at 06/1555Z continues. The maximum observed flux so far is 1980 pfu at 07/1930Z. The greater than 100 MeV proton flux crossed the 1 pfu event threshold at 07/0115Z, with a maximum observed flux so far of 19 pfu at 07/1610Z. C. Geomagnetic Activity Summary: The geomagnetic field has been unsettled to active with isolated minor storm periods observed at high latitudes. D. Stratwarm: Not Available E.
