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.

B. Proton Events
The 10 MeV and 100 MeV proton events which began late on 8 November are still in progress. The 100 MeV proton event peaked at 347 pfu at 09/0350 UTC, declining to a current level of 13 pfu. The 10 MeV proton event peaked at 13,300 pfu at 09/1600 UTC and has slowly declined to a current level of 2962 pfu.
C. Geomagnetic Activity Summary
The geomagnetic field was quiet to active. Active conditions occurred during the 09/1500 - 1800 UTC period. A polar cap absorption event was associated with the proton event. Peak absorption was estimated to be 33 dB at 09/1640 UTC.
