Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 0814 0857 0926 1762 S32W51 M1.3 1f 460 79 IV 1002 1327 IV B. Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field was quiet to unsettled D. Stratwarm: Not Available E. Daily Indices: (real-time preliminary/estimated values) 10 cm 109 SSN 081 Afr/Ap 009/006 X-ray Background B2.6 Daily Proton Fluence (flux accumulation over 24 hrs) GT 1 MeV 8.4e+05 GT 10 MeV 1.1e+04 p/(cm2-ster-day) (GOES-15 satellite synchronous orbit W135 degrees) Daily Electron Fluence GT 2 MeV 1.16e+09 e/(cm2-ster-day) (GOES-15 satellite synchronous orbit W135 degrees) 3 Hour K-indices: Boulder 3 2 1 2 2 2 2 2 Planetary 3 2 1 1 2 1 1 1 F. Comments: The greater than 2 MeV electron fluence at geosynchronous orbit reached very high levels during the period. Particle measurements were being reported from the GOES-15 spacecraft until approximately 05/1730Z when GOES-13 returned as the primary particle monitor.
