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 112 Publicado el 2200Z a las 22 APR 1998IA. Análisis de regiones solares activas y de actividad desde 21-2100Z hasta 22-2100Z SOLAR ACTIVITY WAS VERY LOW. REGION 8205 (N21W66)
PRODUCED SEVERAL MINOR B-CLASS X-RAY SUBFLARES. THIS REGION DOUBLED
IN WHITE LIGHT AREA SINCE YESTERDAY BUT HAS CHANGED VERY LITTLE IN
OVERALL COMPLEXITY. NEW REGION 8208 (N18E57), A SINGLE AXX SPOT
GROUP, WAS NUMBERED TODAY. REMAINING REGIONS WERE STABLE.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO REMAIN
VERY LOW.
IIA. Resumen de la actividad geofísica 21-2100Z a 22-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. THE GREATER THAN 10 MEV
PROTON EVENT THAT BEGAN ON 20/1130Z, IS STILL IN PROGRESS. THE EVENT
CONTINUES TO DECLINE AND IS CURRENTLY AT 220 PFU. THE GREATER THAT
100 MEV EVENT ENDED AT 22/0430Z. THE POLAR CAP ABSORPTION DURING
THIS EVENT REACHED A MAXIMUM OF 13 DB AT 21/1200Z AND REMAINS IN
PROGRESS AT 3.2DB.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED. OCCASIONAL ACTIVE PERIODS ARE
EXPECTED TOMORROW THROUGH FRIDAY AS AN EXTENSION TO THE SOUTHERN
CORONAL HOLE MOVES INTO A FAVORABLE GEOEFFECTIVE POSITION. THE
PROTON EVENT IN PROGRESS IS EXPECTED TO END TOMORROW.
