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 251 Issued at 0245Z on 08 Sep 2005 This report is compiled from data received at SWO on 07 SepA. Energetic Events
Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 1717 1740 1803 0808 S06E89 X17.0 3b 3200 27000 II/IV 1932 2202 0044 M1.4 2006 2007 2007 220
B. Proton Events
A slow rise in the greater than 10 and greater
than 100 MeV protons at geosynchronous orbit began late in the
period. The greater than 10 MeV protons will likely cross the 10 pfu
threshold on 08 Sep.
C. Geomagnetic Activity Summary
The geomagnetic field was quiet to
active. Today's powerful X17 flare produced a sudden disturbance in
the geomagnetic field at 07/1725Z. This 82 nT magnetic crochet was
one of the largest observed this Solar Cycle.
