Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field was at quiet to unsettled levels. Solar wind speed has continued to gradually decrease, ending the period near 525 km/s. The greater than 2 MeV electron flux at geo-synchronous orbit reached high levels. D. Stratwarm: None E. Daily Indices: (real-time preliminary/estimated values) 10 cm 183 SSN 139 Afr/Ap 010/011 X-ray Background C1.4 Daily Proton Fluence (flux accumulation over 24 hrs) GT 1 MeV 4.6e+05 GT 10 MeV 1.1e+04 p/(cm2-ster-day) (GOES-8 satellite synchronous orbit W75 degrees) Daily Electron Fluence GT 2 MeV 7.20e+07 e/(cm2-ster-day) (GOES-8 satellite synchronous orbit W75 degrees) 3 Hour K-indices: Boulder 2 3 3 2 2 3 2 2 Planetary 2 3 3 2 3 3 3 3 F. Comments: Daily X-Ray Background Flux value is estimated from plotted data, pending repair of the automated algorithm. Repair is in progress. SSN is estimated based on SRS data.
