Solar activity 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.

IA. Analysis of Solar Active Regions and Activity from 21-2100Z to 22-2100Z

Solar activity was low with only a few weak C-class X-ray flares. Region 9354 (S09W45) maintained its size, but lost much of the magnetic complexity that had developed yesterday. New region 9361 (S17E07) was numbered today.
