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 264 Publicado el 2200Z a las 21 SEP 1998IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z SOLAR ACTIVITY WAS LOW. THE LARGEST AND MOST ACTIVE
REGION CURRENTLY VISIBLE, REGION 8340 (N19E25), PRODUCED A C2/SF AT
21/0806UT AND A C2/1F AT 21/1842UT. THIS REGION IS STILL UNDERGOING
SLOW GROWTH AND IS CURRENTLY A DKO GROUP COVERING 540 MILLIONTHS OF
WHITE LIGHT AREA. REMAINING REGIONS WERE QUIET.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO REMAIN
LOW. CONTINUED C-CLASS ACTIVITY IS EXPECTED FROM REGION 8340 WITH A
SLIGHT CHANCE FOR AN M-CLASS.
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED WITH ISOLATED ACTIVE
PERIODS IN HIGH LATITUDES.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO REMAIN QUIET TO UNSETTLED WITH OCCASIONAL ACTIVE PERIODS
AT HIGH LATITUDES.
