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. Very stable solar wind conditions persisted through the period. Solar wind speed declined to near 300 km/s and IMF Bz remains near zero. D. Stratwarm: None E. Daily Indices: (real-time preliminary/estimated values) 10 cm 092 SSN 051 Afr/Ap 003/003 X-ray Background A7.9 Daily Proton Fluence (flux accumulation over 24 hrs) GT 1 MeV 7.9e+05 GT 10 MeV 1.4e+04 p/(cm2-ster-day) (GOES-11 satellite synchronous orbit W101 degrees) Daily Electron Fluence GT 2 MeV 6.00e+08 e/(cm2-ster-day) (GOES-12 satellite synchronous orbit W74 degrees) 3 Hour K-indices: Boulder 0 1 1 1 1 2 1 1 Planetary 0 1 1 1 1 0 1 1 F. Comments: The greater than 2 MeV electron fluence at geosynchronous orbit was at high levels.
