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.

None
C. Geomagnetic Activity Summary
The geomagnetic field is expected
to be quiet to unsettled on the first day of the forecast period
with active conditions expected on the second and third day due to
recurrent coronal hole effects.
