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 282 Issued at 0245Z on 09 Oct 2001 This report is compiled from data received at SWO on 08 OctA. Energetic Events
Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 0527 0534 0548 C1.3 130 0809 0819 0838 C4.3 30 II
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 unsettled levels with isolated active periods between 08/1200 and
2400 UTC. High speed stream effects are believed to be responsible
for the slightly elevated field levels.
D. Stratwarm
