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 quiet to active. Isolated active periods were due to continued effects of a coronal hole high speed stream. D. Stratwarm: Not Available E. Daily Indices: (real-time preliminary/estimated values) 10 cm 077 SSN 039 Afr/Ap 012/013 X-ray Background A3.2 Daily Proton Fluence (flux accumulation over 24 hrs) GT 1 MeV 1.4e+06 GT 10 MeV 1.5e+04 p/(cm2-ster-day) (GOES-11 satellite synchronous orbit W104 degrees) Daily Electron Fluence GT 2 MeV 1.10e+09 e/(cm2-ster-day) (GOES-12 satellite synchronous orbit W75 degrees) 3 Hour K-indices: Boulder 3 4 1 3 3 3 3 3 Planetary 3 4 1 1 3 3 3 3 F. Comments: The greater than 2 MeV electron fluence at geosynchronous orbit reached very high levels.
