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 269 Publicado el 2200Z a las 26 SEP 1998IA. Análisis de regiones solares activas y de actividad desde 25-2100Z hasta 26-2100Z SOLAR ACTIVITY WAS VERY LOW TO LOW. SEVERAL SMALL
C-CLASS X-RAY AND SUB-FAINT FLARES OCCURRED FROM REGION 8340
(N21W40). A LARGE NUMBER OF FILAMENTS ARE ALSO ASSOCIATED WITH THIS
REGION.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW
WITH A POSSIBILITY OF ISOLATED M-CLASS FLARES.
IIA. Resumen de la actividad geofísica 25-2100Z a 26-2100Z
THE GEOMAGNETIC FIELD WAS MOSTLY QUIET TO UNSETTLED WITH A SINGLE
ACTIVE PERIOD. THE ACTIVE PERIOD CORRESPONDED TO AN INCREASE IN
SOLAR WIND SPEED AND TEMPERATURE AND A DECREASE IN DENSITY (A
CORONAL HOLE EFFECT). HIGH LATITUDES EXPERIENCED ADDITIONAL
ISOLATED ACTIVE PERIODS.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED WITH ISOLATED ACTIVE PERIODS IN
THE HIGHER LATITUDES.
