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 24 nT sudden impulse was observed on the
boulder magnetometer at 12/2243 UTC. The sudden impulse is likely
the result of a weak CME shock passage.
