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 unsettled. The solar wind speed is still elevated around 500 km/s due to the continued influence of a geoeffective high speed coronal hole stream. D. Stratwarm: None. E. Daily Indices: (real-time preliminary/estimated values) 10 cm 092 SSN 016 Afr/Ap 008/010 X-ray Background A9.2 Daily Proton Fluence (flux accumulation over 24 hrs) GT 1 MeV 3.6e+05 GT 10 MeV 1.5e+04 p/(cm2-ster-day) (GOES-11 satellite synchronous orbit W106 degrees) Daily Electron Fluence GT 2 MeV 2.70e+06 e/(cm2-ster-day) (GOES-12 satellite synchronous orbit W75 degrees) 3 Hour K-indices: Boulder 3 3 2 3 1 2 2 2 Planetary 3 3 2 2 2 3 2 2 F.
