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. Solar wind speed remains elevated, but gradually declined
from near 620 km/s to 500 km/s to end the period.

F. Comments
The energetic event in section A was likely associated with a large backsided halo CME from old Region 720 (N13, L=178), which is due to return to the visible disk on 05 February.
