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 flux values
observed a slight enhancement that was likely
associated with the
M5 flare from Region 2673, but remained below alert thresholds.
C. Geomagnetic Activity Summary
The geomagnetic field was at quiet
to unsettled levels with an isolated active periods, likely
associated with sustained -Bz.
