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 238 Publicado el 2200Z a las 25 AUG 2000IA. Análisis de regiones solares activas y de actividad desde 24-2100Z hasta 25-2100Z SOLAR ACTIVITY BECAME MODERATE. REGION 9143 (S19E59)
PRODUCED AN M1/1N AT 25/1435Z. THIS EVENT WAS ACCOMPANIED BY A TYPE
II/IV AND A 130 SFU BURST AT 2695 MHZ. A LARGE DENSE MASS EJECTION
FOLLOWED THE EVENT AND WAS SEEN TO PROPAGATE PRIMARILY OFF THE EAST
LIMB NEAR THE EQUATOR. PRIOR TO THIS EVENT, REGION 9143 WAS
PREDOMINANTLY STABLE. A LARGE FILAMENT NEAR N37W21 ERUPTED BETWEEN
25/0955-1123Z. THIS FILAMENT ELEVATED AND BECAME MORE DENSE FOR AT
LEAST A DAY BEFORE THE ERUPTION. A SMALL REGION BEGAN TO EMERGE
RAPIDLY NEAR N25E14 AND WAS NUMBERED AS NEW REGION 9144.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY SHOULD BE PREDOMINANTLY
LOW. OBVIOUSLY, REGION 9143 IS CAPABLE OF GENERATING M-CLASS
EVENTS. HOWEVER, THE LACK OF OBVIOUS GROWTH AND MAGNETIC SIMPLICITY
ARGUE FOR ONLY ISOLATED M-CLASS EVENTS FROM THIS REGION.
IIA. GEOPHYSICAL ACTIVITY SUMMARY 24/2100Z TO 25/2100Z:
THE GEOMAGNETIC FIELD WAS QUIET. SOLAR WIND VELOCITY WAS STEADY NEAR
400 KM/S.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED FOR THE NEXT THREE DAYS. AT THIS
TIME, THE MASS EJECTION OBSERVED TODAY IS NOT PROJECTED TO IMPACT
THE EARTH.
