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 with isolated active periods. The disturbed periods are due to a large transequatorial coronal hole, which is producing solar wind speeds generally ranging between 500 - 600 km/s. D. Stratwarm: Not Available E. Daily Indices: (real-time preliminary/estimated values) 10 cm 076 SSN 012 Afr/Ap 010/008 X-ray Background A1.7 Daily Proton Fluence (flux accumulation over 24 hrs) GT 1 MeV 3.7e+05 GT 10 MeV 1.4e+04 p/(cm2-ster-day) (GOES-11 satellite synchronous orbit W110 degrees) Daily Electron Fluence GT 2 MeV 8.30e+06 e/(cm2-ster-day) (GOES-12 satellite synchronous orbit W75 degrees) 3 Hour K-indices: Boulder 1 3 3 1 4 2 1 2 Planetary 0 2 3 1 3 2 2 1 F.
