Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 1508 1521 1536 1432 N14E05 M2.8 1n 160 72 B. Proton Events: The greater than 100 MeV event that began at 13/1810Z, reached a peak value of 1 pfu at 13/1905Z, and ended at 13/2255Z The 10 MeV proton event greater than 100 pfu (S2-Moderate) event began at 13/1855Z, reached a peak value of 469 pfu at 13/2045Z, and dropped below 100 pfu into S1-Minor threshold at 14/0955Z. The S1-Minor storming level remains in progress as of the close of this period. C. Geomagnetic Activity Summary: Field activity was mostly quiet to unsettled in the mid latitudes with periods of active levels at high latitudes. D. Stratwarm: Not Available E.
