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 283 Issued at 0245Z on 10 Oct 2001 This report is compiled from data received at SWO on 09 OctA. Energetic Events
Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 0724 0741 0750 9657 N19E67 C7.0 Sf 125 12 II 1046 1113 1149 9653 S28E08 M1.4 2f 25 130 II/IV
B. Proton Events
The greater than 10 MeV proton flux at
geosynchronous orbit remained at elevated levels but below the
proton event threshold of 10 pfu.
C. Geomagnetic Activity Summary
The geomagnetic field was at quiet
to active levels. High speed stream effects are believed to be
responsible for the elevated field levels.
