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
Geomagnetic activity was at quiet
to minor storm levels. Quiet to unsettled conditions persisted
until 11/1700 UTC when a 11 nT sudden impulse was observed. Active
to minor storming conditions have persisted since the shock which is
believed to be associated with the 09/1113 UTC M1/2f flare and CME.
