Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 1623 1623 1623 240 B. Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field was at predominantly quiet levels. The Boulder magnetometer recorded an active period between 26/0300 and 0600Z. The greater than 2 MeV electron fluxes at geosynchronous orbit reached high levels today. D. Stratwarm: None E.
