Joint USAF/NOAA Solar and Geophysical Activity Summary
SGAS Number 047 Issued at 0245Z on 16 Feb 2004
This report is compiled from data received at SWO on 15 Feb
A. Energetic Events
Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep
0245 0245 0246 910

B. Proton Events: None
C. Geomagnetic Activity Summary: The geomagnetic field was at
predominantly unsettled to minor storm levels. This disturbance
began on 12 February following the onset of a high speed coronal
hole stream. Solar wind speeds this period generally ranged from 650
to 700 km/s.
D. Stratwarm: None
E. Daily Indices: (real-time preliminary/estimated values)
10 cm 102 SSN 075 Afr/Ap 023/018 X-ray Background B1.1
Daily Proton Fluence (flux accumulation over 24 hrs)
GT 1 MeV 1.4e+06 GT 10 MeV 1.3e+04 p/(cm2-ster-day)
(GOES-11 satellite synchronous orbit W101 degrees)
Daily Electron Fluence
GT 2 MeV 6.70e+08 e/(cm2-ster-day)
(GOES-12 satellite synchronous orbit W75 degrees)
3 Hour K-indices:
Boulder 5 4 4 4 2 4 2 3 Planetary 4 4 3 5 3 3 3 2
F. Comments: The greater than 2 MeV electron fluence at
geosynchronous orbit was at high levels.
