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 ranged from
quiet to major storm levels. Geomagnetic storming occurred between
03/0000 - 0600 UTC after a period of sustained southward Bz. Solar
wind speed showed a steady decline with initial values around 675
km/s to day-end values around 550 km/s. The total interplanetary
magnetic field at ACE declined throughout the period, ending the day
at about 5 nT.
