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
Proton levels are high. A 10 MeV proton event
began at 23/0530Z and reached a peak of 3630 pfu at 23/2330Z and
remains elevated. A 100 MeV proton event began at 23/0445Z and
reached a maximum of 2.3 pfu at 23/0750Z before decreasing below the
1 pfu threshold.
C. Geomagnetic Activity Summary
The geomagnetic field began the
period at minor storm levels and then decreased to mostly quiet for
the remainder of the day.
