Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 0446 0451 0453 0139 N12E31 M2.4 1n B. Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field was at quiet to minor storm levels. A six-hour period of southward Bz (02Z to 08Z) was associated with a sector boundary crossing and resulted in active to minor storm conditions (03Z to 09Z). Greater than 2 MeV electron flux at geo-synchronous orbit reached high levels today. D. Stratwarm: None E.
