Proton Events: None. C. Geomagnetic Activity Summary: The geomagnetic field was at quiet to unsettled levels with an isolated active period and middle latitudes during the 29/0900 - 1200Z period. D. Stratwarm: Not Available E. Daily Indices: (real-time preliminary/estimated values) 10 cm 147 SSN 105 Afr/Ap 007/006 X-ray Background B6.5 Daily Proton Fluence (flux accumulation over 24 hrs) GT 1 MeV 6.6e+05 GT 10 MeV 1.3e+04 p/(cm2-ster-day) (GOES-13 satellite synchronous orbit W75 degrees) Daily Electron Fluence GT 2 MeV 7.40e+05 e/(cm2-ster-day) (GOES-13 satellite synchronous orbit W75 degrees) 3 Hour K-indices: Boulder 1 2 3 4 2 2 2 2 Planetary 1 2 3 3 1 1 1 1 F. Comments: Planetary K indices from 1800-2400Z are not available due to network issues, NOAA Kp estimates were used during those times. The daily Ap is estimated.
