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 249 Issued at 0245Z on 06 Sep 2003 This report is compiled from data received at SWO on 05 SepA. Energetic Events

None
C. Geomagnetic Activity Summary
The geomagnetic field was quiet to
active. Solar wind speed is in gradual decline as the associated
coronal hole moves out of a geoeffective position. Solar wind speed
declined from almost 700 km/s to near 600 km/s over the past 24
hours.
