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 minor storming levels for the first period. Active levels were recorded through the next two periods followed by two periods of minor storming levels. The next two periods saw the geomagnetic field in unsettled levels with the final period seeing active levels. D. Stratwarm: Not Available E. Daily Indices: (real-time preliminary/estimated values) 10 cm 109 SSN 071 Afr/Ap 019/029 X-ray Background B3.5 Daily Proton Fluence (flux accumulation over 24 hrs) GT 1 MeV 7.0e+06 GT 10 MeV 1.0e+04 p/(cm2-ster-day) (GOES-13 satellite synchronous orbit W75 degrees) Daily Electron Fluence GT 2 MeV 5.00e+08 e/(cm2-ster-day) (GOES-13 satellite synchronous orbit W75 degrees) 3 Hour K-indices: Boulder 5 5 4 4 4 3 2 3 Planetary 5 4 4 5 5 3 3 4 F.
