Geophysical report
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

Joint USAF/NOAA Solar and Geophysical Activity Summary
SGAS Number 209 Issued at 0245Z on 28 Jul 2005 This report is compiled from data received at SWO on 27 JulA. Energetic Events
Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep
B. Proton Events
A slow gradual rise in the greater than 10 MeV
protons began after the M3.7 event at 27/0502 UTC. The 10 pfu alert
threshold was finally reached at 27/2300 UTC. The max flux at the
time of issue for the greater than 10 MeV was 14 pfu.
C. Geomagnetic Activity Summary
The geomagnetic field was quiet to
minor storm conditions.
