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 ranged from
quiet to major storm levels. And extended interval of active
conditions, with an isolated period of major storming at high
latitudes, appeared to occur primarily due to a sustained strong
southward orientation of Bz, and a slow increase in solar wind
speed. Other solar wind data suggest an overall pattern of a CIR
evolving toward to a weak high speed stream pattern near the end of
the period.
