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 337 Issued at 2200Z on 03 DEC 1997IA. Analysis of Solar Active Regions and Activity from 02-2100Z to 03-2100Z SOLAR ACTIVITY WAS LOW. REGION 8313 (N20W16) PRODUCED
OCCASIONAL C-CLASS SUBFLARES. THE REGION DECLINED IN SPOT COUNT
DURING THE PERIOD, BUT RETAINED A MODERATELY COMPLEX MAGNETIC
STRUCTURE. NEW REGION 8114 (S30E04) WAS ASSIGNED.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. REGION 8113 IS CAPABLE OF M-CLASS FLARE ACTIVITY. THE
REGION COULD PRODUCE AN ISOLATED MAJOR FLARE AS WELL.
IIA. Geophysical Activity Summary 02-2100Z to 03-2100Z
THE GEOMAGNETIC FIELD HAS BEEN QUIET FOR THE PAST 24 HOURS.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE MOSTLY QUIET FOR THE NEXT 3 DAYS.
