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 at quiet to minor storm conditions. Increased activity was due to the continued influence of a recurrent coronal hole high speed stream. Solar wind speed at ACE is currently elevated around 660 km/s. D. Stratwarm: Not Available E. Daily Indices: (real-time preliminary/estimated values) 10 cm 085 SSN 018 Afr/Ap 015/023 X-ray Background A4.5 Daily Proton Fluence (flux accumulation over 24 hrs) GT 1 MeV 4.0e+06 GT 10 MeV 1.7e+04 p/(cm2-ster-day) (GOES-11 satellite synchronous orbit W135 degrees) Daily Electron Fluence GT 2 MeV 5.00e+08 e/(cm2-ster-day) (GOES-12 satellite synchronous orbit W75 degrees) 3 Hour K-indices: Boulder 5 4 5 5 2 1 2 3 Planetary 5 5 5 4 2 2 2 3 F.
