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
A greater than 100 MeV proton event began at
16/2125Z following yesterday's M4 flare. The event ended at 17/0730Z
with a peak flux of 2.9 pfu at 16/2315Z. A greater than 10 MeV
proton event began at 16/2200Z, peaked at 17/0500Z at 44 pfu, and
ended at 17/1805Z.
C. Geomagnetic Activity Summary
The geomagnetic field was quiet to
active. The most disturbed conditions occurred early in the period
during intervals of sustained southward Bz. The elevated solar wind
conditions are due to the combined effects of CME transient flow and
a high speed coronal hole stream.
