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 231 Issued at 0245Z on 19 Aug 2005 This report is compiled from data received at SWO on 18 AugA. Energetic Events
Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep
B. Proton Events
None
C. Geomagnetic Activity Summary
The geomagnetic field was quiet to
active due to the continued influence of a coronal hole high speed
stream. Solar wind speed at ACE has gradually decreased from
approximately 700 km/s to 620 km/s.
