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 minor storm levels. Minor storming occurred between
0600 - 1200 UTC as Bz fluctuated between +/- 5 nT and the solar wind
speed increased from about 550 km/s to 750 km/s. At time of issue,
solar wind speed was about 625 km/s.
