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 geomagnmetic field was quiet
to unsettled. We have been under the influence of a high speed
coronal hole stream for almost 40 hours, but the geomagnetic
response so far has been weak.
