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 quiet
to unsettled levels. A single isolated active period was observed
at higher latitudes between 12/1500 to 1800Z. The greater than 2
MeV electron fluxes at geosynchronous orbit reached high levels
again today.
