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 052 Publicado el 2200Z a las 21 FEB 1998IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z SOLAR ACTIVITY WAS VERY LOW. ISOLATED B-CLASS X-RAY
BURSTS WERE DETECTED WITH NO OPTICAL ASSOCIATIONS. REGION 8156 (S25
W72) APPEARED TO BE IN A PERIOD OF GRADUAL DECAY, LOSING A FEW
SPOTS. NEW REGION 8162 (S32E46), A SMALL, STABLE B-CLASS GROUP, WAS
NUMBERED. A CORONAL MASS EJECTION (CME) WAS DETECTED BEGINNING
AROUND 21/0200UT. MOST OF THE MASS WAS SEEN DEPARTING THE WEST LIMB,
SLIGHTLY DECLINED TO THE ECLIPTIC.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE VERY
LOW TO LOW WITH REGION 8156 PROVIDING A FAIR CHANCE FOR AN ISOLATED
C-CLASS SUBFLARE.
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z
THE GEOMAGNETIC FIELD WAS QUIET AT ALL LATITUDES. THE GREATER THAN 2
MEV ELECTRON FLUX INCREASED TO HIGH LEVELS BEGINNING 21/1812UT.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE MOSTLY QUIET THROUGH 23 FEBRUARY. ACTIVITY IS
EXPECTED TO INCREASE TO UNSETTLED LEVELS ON THE FINAL DAY OF THE
FORECAST PERIOD. THE GREATER THAN 2 MEV ELECTRON FLUX IS EXPECTED TO
DECLINE TO MODERATE TO NORMAL LEVELS EARLY IN THE PERIOD.
