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 049 Publicado el 2200Z a las 18 FEB 1998IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z SOLAR ACTIVITY WAS LOW. REGION 8156 (S25W34), CURRENTLY
A 16-SPOT 'EHI' BETA-GAMMA, GENERATED THREE C-CLASS EVENTS DURING
THE PAST 24 HOURS, THE LARGEST A C5/1F AT 18/1138Z.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO REMAIN
LOW, WITH A GOOD PROBABILITY FOR CONTINUED C-CLASS ACTIVITY FROM
REGION 8156.
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
THE GEOMAGNETIC FIELD HAS BEEN MOSTLY UNSETTLED TO ACTIVE DURING THE
PAST 24 HOURS, WITH AN ISOLATED PERIOD OF MINOR TO MAJOR STORMING
RECORDED DURING THE INTERVAL 18/0000-0300Z. THIS DISTURBANCE IS
THOUGHT TO BE RELATED TO THE CORONAL MASS EJECTION ACTIVITY OF 14
FEBRUARY.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED FOR THE NEXT 12 HOURS, AND MOSTLY
QUIET THEREAFTER FOR THE REMAINDER OF THE FORECAST PERIOD.
