Energetic Events Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 2230 2236 2240 1760 N12E68 C2.9 Sf 2000 B. Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field was quiet D. Stratwarm: Not Available E. Daily Indices: (real-time preliminary/estimated values) 10 cm 107 SSN 083 Afr/Ap 002/002 X-ray Background B2.7 Daily Proton Fluence (flux accumulation over 24 hrs) GT 1 MeV 2.0e+06 GT 10 MeV 1.1e+04 p/(cm2-ster-day) (GOES-15 satellite synchronous orbit W135 degrees) Daily Electron Fluence GT 2 MeV 2.50e+09 e/(cm2-ster-day) (GOES-15 satellite synchronous orbit W135 degrees) 3 Hour K-indices: Boulder 0 0 0 1 1 2 1 1 Planetary 1 0 0 0 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.
