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
predominantly active to major storm levels with an isolated severe
storm period between 04/00 - 03Z. Though solar wind speed remains
below 450 km/s, the Bz component of the interplanetary magnetic
field was sustained southward for the entire period, ranging -2 to
-12nT. The storm was gradually subsiding by the end of the period.
