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 major storm levels. An isolated major storm period was observed between 26/1500 UTC and 26/1800 UTC. The heightened activity was due to the influence of a high speed coronal hole stream. D. Stratwarm: Not Available E.
