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.

C. Geomagnetic Activity Summary
The geomagnetic field was quiet to
active. Solar wind speed was near 600 km/s early in the period,
which accounted for the active periods. Speed declined to near 450
km/s by the end of the period. The field responded to the declining
solar wind speed by returning to mostly quiet levels.
