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 043 Publicado el 2200Z a las 12 FEB 1998IA. Análisis de regiones solares activas y de actividad desde 11-2100Z hasta 12-2100Z SOLAR ACTIVITY WAS VERY LOW. NUMEROUS B-CLASS X-RAY
BURSTS OCCURRED, FOUR OF WHICH WERE OPTICALLY ASSOCIATED WITH
SUBFLARES FROM REGION 8156 (S24E43). REGION 8156 CONTINUED TO
DISPLAY MINOR GROWTH IN SPOT COUNT AND FIELD INTENSITY. NO NEW
REGIONS WERE NUMBERED.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE VERY
LOW TO LOW. REGION 8156 MAY PRODUCE C-CLASS SUBFLARES.
IIA. Resumen de la actividad geofísica 11-2100Z a 12-2100Z
THE GEOMAGNETIC FIELD WAS AT QUIET TO UNSETTLED LEVELS DURING MOST OF
THE PERIOD. HOWEVER, FIELD ACTIVITY INCREASED TO ACTIVE TO MINOR
STORM LEVELS DURING 12/0000-0300UT AND 12/1100-1300UTWITH THE MINOR
STORM LEVELS LIMITED TO HIGH LATITUDES. THE GREATER THAN 2 MEV
ELECTRON FLUX REACHED HIGH LEVELS AT 12/1722UT.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED DURING MOST OF THE PERIOD.
HOWEVER, ACTIVE PERIODS ARE POSSIBLE DURING THE LAST TWO DAYS OF THE
FORECAST PERIOD. THE GREATER THAN 2 MEV ELECTRON FLUX IS EXPECTED TO
BE AT MODERATE TO HIGH LEVELS.
