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 270 Publicado el 2200Z a las 27 SEP 1998IA. Análisis de regiones solares activas y de actividad desde 26-2100Z hasta 27-2100Z SOLAR ACTIVITY WAS LOW. REGIONS 8340 (N19W54) AND 8346
(S28E01) PRODUCED SEVERAL SMALL AND MODERATE C-CLASS X-RAY,
SUB-FAINT AND 1F FLARES. A C2.6/SF FLARE FROM 8340 PRODUCED AN
ASSOCIATED TEN FLARE.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE VERY
LOW TO LOW WITH A POSSIBILITY OF ISOLATED M-CLASS FLARES.
IIA. Resumen de la actividad geofísica 26-2100Z a 27-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED THROUGHOUT THE PERIOD.
ELEVATED SOLAR WIND SPEEDS CONTINUE TO GENERATE THE POSSIBILITY OF
ACTIVE PERIODS AT MID-LATITUDE STATIONS.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED WITH ISOLATED ACTIVE PERIODS IN
THE HIGHER LATITUDES.
