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 311 Issued at 0245Z on 07 Nov 2001 This report is compiled from data received at SWO on 06 NovA. Energetic Events

B. Proton Events
The greater than 10 MeV proton event peaked at
31,700 pfu at 06/0215 UTC. The greater than 100 MeV proton event
peaked at 253 pfu at 06/0220 UTC. Both proton events levels declined
sharply during the period but continued through the end of the day.
A polar cap absorption event remained in effect.
C. Geomagnetic Activity Summary
The geomagnetic field was at
unsettled to severe storm conditions. The full-halo coronal mass
ejection (CME) from the 04 November event impacted the geomagnetic
field at 06/0150 UTC. This was indicated by a 90 nT sudden impulse
as measured by the USGS Boulder magnetometer. Severe geomagnetic
storming occurred between 06/0000 and 06/0600 UTC and 15-1800 UTC.
