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 at 10 pfu proton event
began at 07/0400Z amd reached a maximum of 25 pfu 07/0745Z. The
flux at geosynchronous orbit has been steadily declining since, but
remains within +/- 2 pfu of the 10 MeV threshold.
C. Geomagnetic Activity Summary
The geomagnetic field activity
ranged from quiet to unsettled.
