Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep None B. Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field ranged from quiet to minor storm levels. The disturbed conditions were associated with a high speed coronal hole stream. Solar wind speed gradually increased to over 600 km/s following the onset of the high speed stream midday on 06 May. D. Stratwarm: Not Available E.
