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
unsettled to severe storm levels. The most disturbed period was from
21/0600 to 0900 UTC. ACE solar wind data indicates the gradual onset
of a coronal hole high-speed-stream over the past 24 hours. Current
solar wind parameters include speed at about 700 km/s, density from
1 to 5 p/cc, and Bz fluctuating between +/- 10 nT.
