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 at
geosynchronous orbit reached the greater than 10 pfu threshold at
20/0850Z, reached a peak of 22 pfu at 20/0925Z, and dropped below
the S1 event threshold at 20/1125Z. This proton event was associated
with the M3/Sn at 20/0756Z from Region 1976.
C. Geomagnetic Activity Summary
The geomagnetic field was at quiet
to major storm levels.
