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 quiet to
active with an isolated minor storm period between O600Z and 0900Z.
This elevated activity was due to persistence of a coronal hole high
speed stream. Solar wind speed at ACE fluctuated around 700 to 750
km/s throughout the period. Bz was oscillating between +/- 5 nT.
