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 activity was
at quiet to unsettled levels. The greater than 2 MeV electron flux
observed at geosynchronous orbit continued a steady drop from
moderately enhanced levels today.
