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 28-2100Z to 01-2100Z

SOLAR ACTIVITY WAS LOW. REGION 8169 (S21W72) PRODUCED TWO C-CLASS SUBFLARES AROUND MID PERIOD. OTHERWISE, OCCASIONAL B-CLASS X-RAY BURSTS OCCURRED. REGION 8171 (S23W23) DISPLAYED GRADUAL GROWTH THROUGH THE PERIOD. REGIONS 8172 (N22E05) AND 8173 (S17E71) WERE NUMBERED.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE LOW. REGIONS 8169 AND 8171 ARE CAPABLE OF C-CLASS FLARE PRODUCTION.
