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
predominantly quiet to unsettled levels. An isolated active period
occurred at mid and high latitudes between 10/1200 and 1500Z. The
greater than 2 MeV electron fluxes at geosynchronous orbit reached
high levels today.
