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 and
associated polar cap absorption remained in progress at the end of
the period (proton flux peaked to 18900 pfu at 24/0555 UTC).
C. Geomagnetic Activity Summary
The geomagnetic field was at quiet
to unsettled levels with an isolated period of active
(24/2100-25/0000 UTC). A moderate (10.2 percent based on the
Thule neutron monitor) Forbush decrease began shortly after the
beginning of forecast period and peaked near 25/0040 UTC, ended near
25/0300 UTC.
