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 233 Publicado el 2200Z a las 21 AUG 1999IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z SOLAR ACTIVITY WAS HIGH. REGION 8674 (S24E66) PRODUCED
AN M9.8/1N EVENT WITH AN ACCOMPANYING TYPE II SWEEP (700 KM/S) AT
20/2310, AND A 480 SFU 10 CM BURST. REGION 8674 ALSO PRODUCED AN
M3/1B EVENT WITH AN ACCOMPANYING WEAK TYPE II (500 KM/S), AND A 290
SFU 10CM BURST AT 21/1634UT. THE ONLY OTHER REGION OF NOTE WAS
REGION 8668 (N22W11) WHICH PRODUCED A 7 DEGREE DISAPPEARING SOLAR
FILAMENT WITH AN OPTICAL SUBFLARE AT 21/1416UT.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE
MODERATE WITH AN ISOLATED CHANCE OF AN X-CLASS EVENT FROM REGION
8674.
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z
