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.

Joint USAF/NOAA Solar and Geophysical Activity Summary

B. Proton Events
The greater than 10 MeV proton event that began
on 08/0215Z was further enhanced with today's shock passage, and
reached a peak flux of 1880 pfu at 11/0425Z. The greater than 100
MeV proton that began at 08/0405Z, reached a peak flux of 8 pfu at
09/1920Z, and ended at 11/0545Z.
C. Geomagnetic Activity Summary
The geomagnetic field was at
active to severe storm levels today. The storming periods are most
likely due to the passage of a CME from the X6 flare that occurred
on 09 September.
