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 at
unsettled to minor storm levels early in the day, then at quiet to
unsettled levels thereafter. The isolated minor storm period was
observed at higher latitudes during 10/0300-0600 UTC, in probable
association with a sustained period of southward Bz during that
time.
