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 greater than 10 MeV proton flux reached a
maximum of 657 pfu at 07/2335Z and continues to be above the 10 pfu
threshold.
C. Geomagnetic Activity Summary
The geomagnetic field was at quiet
to severe storm levels due to CME effects.
