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.

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 321 Issued at 2200Z on 16 NOV 1996IA. Analysis of Solar Active Regions and Activity from 15-2100Z to 16-2100Z SOLAR ACTIVITY WAS VERY LOW. NO FLARES OCCURRED.
TWO NEW REGIONS WERE NUMBERED TODAY, 7997 (N08E50), A THREE
SPOT 'BXO' BETA GROUP, AND 7998 (S14E46), A TWO SPOT 'AXX'
ALPHA GROUP. WITH THESE TWO NEW REGIONS, THERE ARE CURRENTLY
FOUR ACTIVE REGIONS ON THE VISIBLE DISK. YESTERDAY'S
CARRYOVER REGIONS, 7995 (S00E05) AND 7996 (N31E05), ARE BOTH
STABLE AS TWO SPOT 'AXX' ALPHA GROUPS.
