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
None
C. Geomagnetic Activity Summary
The geomagnetic field was at
unsettled to major storm levels. Elevated solar wind speed combined
with a period of southward Bz resulted in one period of isolated
major storm levels.
