Informe actividad solar
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.

Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 345 Publicado el 2200Z a las 11 DEC 1998IA. Análisis de regiones solares activas y de actividad desde 10-2100Z hasta 11-2100Z SOLAR ACTIVITY WAS LOW. ONLY MINOR C-CLASS X-RAY EVENTS
OCCURRED DURING THE PERIOD. THE MOST ACTIVE REGIONS WERE 8404
(S22W66), 8405 (S14W08), 8408 (S18E15), AND 8409 (S29E27). EACH OF
THESE REGIONS PRODUCED A C-CLASS X-RAY EVENT AND NUMEROUS OPTICAL
SUBFLARES. REGIONS 8408 AND 8409 HAVE DEVELOPED BETA-GAMMA MAGNETIC
CLASSIFICATIONS. THE REST OF THE REGIONS WERE MOSTLY QUIET AND
STABLE. TWO NEW REGIONS WERE NUMBERED TODAY. REGION 8410 (N23E77) AN
HSX ALPHA GROUP AND REGION 8411(S28E64) AN AXX ALPHA GROUP.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO REMAIN
LOW WITH CONTINUED C-CLASS EVENTS. THERE IS A SLIGHT CHANCE OF AN
ISOLATED M-CLASS EVENT.
IIA. Resumen de la actividad geofísica 10-2100Z a 11-2100Z
THE GEOMAGNETIC FIELD HAS BEEN QUIET TO MOSTLY ACTIVE WITH PERIODS OF
MINOR STORM CONDITIONS AT HIGHER LATITUDES. THESE CONDITIONS MAY
HAVE BEEN THE RESULT OF A CORONAL MASS EJECTION THAT OCCURRED ON THE
NORTH EAST LIMB ON 08 DECEMBER AT 1500UT.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED.
