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 296 Issued at 0245Z on 23 Oct 2001 This report is compiled from data received at SWO on 22 OctA. Energetic Events

B. Proton Events
The greater than 10 MeV proton flux at
geosynchronous orbit exceeded threshold at 22/1910 UTC. At the time
of issue of this bulletin the 10 MeV proton flux was at 16 pfu.
C. Geomagnetic Activity Summary
The geomagnetic field was at minor
to major storm levels. The second CME passage that had been
expected today appears to have been incorporated into the first
creating minor to major storm conditions for the entire period aside
from a couple isolated severe storm conditions at some stations.
