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 event that began
on 08/0215Z reached a peak flux of 1040 pfu at 10/1105Z. The
greater than 100 MeV proton event that began at 08/0405Z reached a
peak flux of 7 pfu at 09/1920Z.
C. Geomagnetic Activity Summary
The geomagnetic field ranged from
quiet to minor storm levels. Southward Bz and continued transient
flow are responsible for the elevated conditions.
