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 weak shock was detected at the L1 position
by the NASA/ACE spacecraft at approximately 31/1100 UTC. The Bz
component of the IMF was northward resulting in little geomagnetic
activity.
