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 100 MeV proton event at
geosynchronous orbit that began at 07/0405Z, reached a maximum of 69
pfu at 07/1525Z, and ended at 10/1650Z. The greater than 10 MeV
proton event at geosynchronous orbit that began at 07/0510Z, reached
a maximum of 6530 pfu at 08/1115Z, was still ongoing at the close of
the period.
C. Geomagnetic Activity Summary
Field activity ranged from quiet
to major storm levels due to continued effects from a CME passage.
