Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 0022 0022 0022 110 0154 0154 0154 100 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 105 SSN 075 Afr/Ap 008/008 X-ray Background B2.6 Daily Proton Fluence (flux accumulation over 24 hrs) GT 1 MeV 1.4e+06 GT 10 MeV 1.2e+04 p/(cm2-ster-day) (GOES-15 satellite synchronous orbit W135 degrees) Daily Electron Fluence GT 2 MeV 2.10e+09 e/(cm2-ster-day) (GOES-15 satellite synchronous orbit W135 degrees) 3 Hour K-indices: Boulder 3 4 3 2 2 2 1 1 Planetary 3 3 2 2 1 2 0 1 F. Comments: The greater than 2 MeV electron fluence at geosynchronous orbit reached very high levels during the summary period. Particle measurements are being reported from the GOES-15 satellite due to a GOES-13 outage.
