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 above 10 pfu
that began at 05/0040Z, reached a maximum of 844 pfu at 08/0035Z and
ended at 09/0005Z. The greater than 10 MeV event crossed the 100
pfu threshold between 05/0715Z and 08/0620Z.
