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 310 Issued at 0245Z on 06 Nov 2001 This report is compiled from data received at SWO on 05 Nov

B. Proton Events
The greater than 100 MeV proton event that started on 04 November continued through out the period and flux levels continued to climb, closing out the day at 116 pfu. The greater than 10 MeV proton event also continued to escalate flux levels, closing the period at 24,300 pfu. Both proton events originated from the X1/3b flare from Region 9684, that occurred on 04/1620 UTC. Subsequent flares may have contributed to the continued proton flux increase. A polar cap absorption event remains in progress.
C. Geomagnetic Activity Summary
The geomagnetic field was at quiet to active levels.
