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 051 Publicado el 2200Z a las 20 FEB 1997IA. Análisis de regiones solares activas y de actividad desde 19-2100Z hasta 20-2100Z SOLAR ACTIVITY WAS LOW AS FOUR C-CLASS X-RAY EVENTS
OCCURRED DURING THE PAST 24 HOURS, THE FIRST AN OPTICALLY CORRELATED
C3 FLARE AT 19/2223Z. THE LARGEST EVENT, A C4 FLARE, OCCURRED AT
20/1144Z. ALL EVENTS EMENATED FROM REGION 8018 (N05W89) WHILE IT
WAS A SINGLE SPOT 'AXX' GROUP. THE REGION HAS SINCE DECAYED INTO A
SPOTLESS PLAGE AS IT ROTATES OFF THE WEST LIMB.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE VERY
LOW.
IIA. Resumen de la actividad geofísica 19-2100Z a 20-2100Z
THE GEOMAGNETIC FIELD HAS BEEN QUIET AT ALL LATITUDES FOR THE PAST 24
HOURS. AN 18-DEGREE LONG FILAMENT AT LOCATION S44W09 DISAPPEARED
FROM THE DISK DURING THE INTERVAL 20/0100-0406Z.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED FOR THE NEXT THREE DAYS, WITH AN
INCREASED CHANCE FOR ISOLATED PERIODS OF ACTIVE CONDITIONS ON DAY
THREE.
