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 active levels with one period of minor storm conditions. A shock
passage was observed by the NASA/ACE spacecraft at 01/0425 UTC and a
corresponding 26 nT sudden impulse was recorded at 01/0511 UTC on
the Boulder magnetometer. Active to minor storm conditions
followed the sudden impulse.
