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 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.
