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 unsettled to active. This weak disturbance is due to a high speed coronal hole stream. Solar wind speeds began the period slightly elevated near 500 km/s, but gradually increased to 650 - 700 km/s by the latter half of the period. D. Stratwarm: None E.
