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 severe storm levels during the past 24 hours. Conditions were initially quiet to unsettled, but increased to active levels after 0300Z, and increased further to major to severe storm levels between 0900-1200Z. Activity declined to active to major storm levels from 1200-1800Z and declined further to mostly quiet to unsettled levels from 1800-2400Z. D. Stratwarm: Not Available E.
