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 minor storm levels. A very weak signature from the NASA/ACE data
indicate a transient may have passed around 28/1200Z although the
elevated geomagnetic conditions are believed to be from a recurrent
coronal hole. The greater than 2 MeV electron fluxes at
geosynchronous orbit have again reached high levels.
