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 113 Publicado el 2200Z a las 23 APR 1999IA. Análisis de regiones solares activas y de actividad desde 22-2100Z hasta 23-2100Z SOLAR ACTIVITY WAS VERY LOW. NO FURTHER DEVELOPMENT WAS
OBSERVED IN REGION 8518 (S14W10) WHICH HAS NOW STABILIZED AS AN
E-TYPE BETA GROUP. OCCASIONAL SURGING AND POINT BRIGHTENINGS WERE
ALSO NOTED IN THIS REGION THROUGHOUT THE PERIOD. NEW REGION 8522
(N16E63) WAS NUMBERED TODAY. REMAINING REGIONS WERE QUIET.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE VERY
LOW TO LOW. REGION 8518 APPEARS TO BE THE ONLY REGION CAPABLE OF
C-CLASS ACTIVITY.
