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
unsettled. The high speed solar wind stream that became geoeffective
yesterday remains in effect. Solar wind speed was approximately 540
km/s, but IMF Bz was predominantly northward.
