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 231 Publicado el 2200Z a las 19 AUG 1999IA. Análisis de regiones solares activas y de actividad desde 18-2100Z hasta 19-2100Z SOLAR ACTIVITY WAS MODERATE. REGION 8672 (N15W17)
PRODUCED AN M1/1N AT 1205Z, BUT LITTLE ELSE. REGION 8668 (N22E01)
STILL DOMINATES THE DISK, BUT WAS STABLE. NEWLY ASSIGNED REGION 8673
(S17E81) ROTATED INTO VIEW. THIS IS THE APPARENT RETURN OF OLD
REGION 8647, THE SITE OF M AND X CLASS ACTIVITY LAST ROTATION.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. MORE ISOLATED M-CLASS EVENTS MAY OCCUR FROM REGIONS
8668 AND 8673.
IIA. Resumen de la actividad geofísica 18-2100Z a 19-2100Z
THE GEOMAGNETIC FIELD WAS AT UNSETTLED TO MINOR STORM LEVELS DURING
THE DAY. THE SOLAR WIND IS STILL GUSTING TO SPEEDS NEAR 800 KM/S,
DRIVING THIS ELEVATED MAGNETIC ACTIVITY. THE GREATER THAN 2 MEV
ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT PERSISTED AT HIGH LEVELS
THROUGHOUT THE PERIOD.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE UNSETTLED TO ACTIVE THE NEXT 24 HOURS. THE CURRENT
DISTURBANCE SHOULD SLOWLY WEAKEN AND YIELD TO UNSETTLED CONDITIONS
BY THE END OF THE INTERVAL.
