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. A declining high speed stream with very low density and weak
northward IMF Bz continues to buffet the Earth's magnetic field.
Solar wind speed declined from near 700 km/s to below 600 km/s by
the end of the period.
