Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 0956 1018 1038 B7.3 II B. Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field was quiet to active. The high speed coronal hole stream that became geoeffective on 05 May continues to buffet the geomagnetic field. Frequent southward IMF Bz oscillations over the last 24 hours are responsible for the most disturbed periods. The high speed stream does appear to be subsiding: solar wind speed decreased to below 500 km/s late in the period. D. Stratwarm: None E.
