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
active to major storm levels. The onset of the expected coronal
hole was marked by a co-rotating interacting region with solar wind
speed increasing to near 600 km/s and a 12 hour period of minor
storm levels. Late in the period indications of a possible shock
passage at the NASA/ACE spacecraft coincided with a major storm
period.
