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 235 Issued at 0245Z on 23 Aug 2005 This report is compiled from data received at SWO on 22 AugA. Energetic Events
Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep
B. Proton Events
The greater than 10 MeV proton flux passed the 10
pfu event threshold at 22/2040 UTC. The flux at 23/0000 UTC was
about 88 pfu.
C. Geomagnetic Activity Summary
The geomagnetic field was quiet to
unsettled with isolated active periods. This activity is believed to
be the result of a high-speed coronal hole stream.
D. Stratwarm
None

F. Comments
Today's observed Penticton 10.7 flux was flare enhanced. The daily background value reported in Part E was estimated to be 105 sfu.
