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 276 Publicado el 2200Z a las 03 OCT 1998IA. Análisis de regiones solares activas y de actividad desde 02-2100Z hasta 03-2100Z SOLAR ACTIVITY REMAINED VERY LOW. ONLY MINOR B-CLASS
ENHANCEMENTS WERE OBSERVED. REGION 8350 (N19E55) WAS GENERALLY
STABLE. SLIGHT MAGNETIC POLARITY MIXING BECAME EVIDENT DURING THE
PERIOD. A MODERATE SIZE FILAMENT LOCATED FROM N51E35-N48E57 FADED
BETWEEN 03/0253-0849Z.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY SHOULD REMAIN
PREDOMINANTLY VERY LOW FOR THE NEXT THREE DAYS. REGION 8350 IS
CAPABLE OF PRODUCING AN ISOLATED C-CLASS FLARE.
IIA. Resumen de la actividad geofísica 02-2100Z a 03-2100Z
THE GEOMAGNETIC FIELD WAS AT UNSETTLED TO ACTIVE LEVELS FOR THE FIRST
HALF OF THE PERIOD. ISOLATED MINOR STORMING WAS OBSERVED DURING THAT
TIME. DURING THE LATTER HALF OF THE PERIOD, THE FIELD WAS QUIET TO
UNSETTLED. SOLAR WIND VELOCITY FELL STEADILY THROUGH THE PERIOD FROM
ABOUT 650 KM/S TO APPROXIMATELY 500 KM/S. IT APPEARS THAT THE
DISTURBANCE EXPECTED TO ARRIVE ON 03 OCT, ACTUALLY ARRIVED ON 02 OCT
NEAR 0700Z. ENERGETIC ELECTRON FLUXES AT GEOSYNCHRONOUS ORBIT
REACHED HIGH LEVELS DURING THE PERIOD.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD SHOULD BE
QUIET TO UNSETTLED FOR THE NEXT THREE DAYS.
