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 278 Issued at 0245Z on 05 Oct 2001 This report is compiled from data received at SWO on 04 OctA. Energetic Events
Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 1413 1423 1427 9644 N18W41 C2.4 Sf 190
B. Proton Events
The greater than 10 MeV proton event that began
on 01 October continued. The peak flux for this event was 2360 pfu
at 02/0810 UTC. The Flux levels remained above event level at the
time of bulletin issue and are gradually decreasing.
C. Geomagnetic Activity Summary
The geomagnetic field was at quiet
to minor storm levels due to CME passage.
