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 at
predominantly unsettled to active levels with isolated high latitude
minor storm periods. A high speed solar wind stream, with winds
ranging from 520 - 600 km/s, continues to buffet the geomagnetic
field.
