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 221 Issued at 0245Z on 09 Aug 2005 This report is compiled from data received at SWO on 08 AugA. Energetic Events
Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep None
B. Proton Events
None
C. Geomagnetic Activity Summary
The geomagnetic field ranged from
quiet to unsettled levels. Solar wind speed has decreased over the
past 24 hours from approximately 600 km/s to 540 km/s as the coronal
hole high speed stream declines.
