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
GOES-13 indicated an enhancement of the greater
than 10 MeV protons starting at 15/0710Z and peaking around 2.6 PFU
at geosynchronous orbit.
C. Geomagnetic Activity Summary
The geomagnetic was mostly quiet
with a few periods at active levels at high latitudes.
