Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep None B. Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field was at quiet to active levels, with isolated minor storm periods at high latitudes. A high speed coronal hole stream is responsible for the disturbed periods. Solar wind speed is in slow decline and ended the period near 600 km/s. D. Stratwarm: Not Available E.
