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
A greater than 10 MeV proton enhancement was
observed in GOES 13 flux data associated with the long duration M1
flare at 22/1110Z from Region 1314, however the proton flux has not
reached the 10 PFU threshold.
