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 057 Publicado el 2200Z a las 26 FEB 2000IA. Análisis de regiones solares activas y de actividad desde 25-2100Z hasta 26-2100Z SOLAR ACTIVITY REMAINED AT A LOW LEVEL. SEVERAL LOW
LEVEL C-CLASS EVENTS OCCURRED. REGION 8891 (S15E60) IS A LARGE
REGION OF OVER 700 MILLIONTHS AREA BUT EXHIBITS A BIPOLAR MAGNETIC
STRUCTURE. REGION 8882 (S16E08) SHOWED SOME MINOR MIXING OF
POLARITIES AND A WEAK DELTA CONFIGURATION MAY EXIST HERE. REGION
8889 (N20E46) IS A MODERATE SIZE E CLASS GROUP WITH A LARGE TRAILING
FILAMENT THAT WAS QUITE ACTIVE AT TIMES DURING THE PERIOD. A LONG
DURATION C2 X-RAY FLARE OCCURRED BETWEEN 26/1036-1222Z. SOHO DATA
INDICATE THIS EVENT ORIGINATED FROM BEHIND THE SOUTHWEST LIMB.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY SHOULD BE LOW TO
MODERATE. M-CLASS EVENTS ARE POSSIBLE FROM REGIONS 8882, 8889, AND
8891. THERE IS ALSO THE POSSIBILITY OF A LONG DURATION C OR M-CLASS
EVENT FROM REGION 8889 SHOULD THE NEARBY FILAMENT ERUPT. THERE IS A
SLIGHT CHANCE OF AN X-CLASS EVENT DURING THE PERIOD. THIS CHANCE
WOULD BECOME GREATER SHOULD REGIONS 8882 AND 8891 BEGIN TO EVOLVE
QUICKLY AND DEVELOP GREATER MAGNETIC COMPLEXITY.
IIA. Resumen de la actividad geofísica 25-2100Z a 26-2100Z
THE GEOMAGNETIC FIELD RANGED FROM QUIET TO ACTIVE LEVELS. SOLAR WIND
VELOCITY CONTINUED TO SLOWLY DECLINE BUT ENDED THE PERIOD STILL
ELEVATED NEAR 600 KM/S. ENERGETIC ELECTRON FLUXES AT GEOSYNCHRONOUS
ORBIT REACHED HIGH LEVELS FOR THE SECOND CONSECUTIVE DAY.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD SHOULD BE
PREDOMINANTLY QUIET TO UNSETTLED FOR 27 FEB. ISOLATED ACTIVE PERIODS
ARE POSSIBLE AS THIS CORONAL HOLE RELATED DISTURBANCE SUBSIDES.
MOSTLY QUIET CONDITIONS ARE EXPECTED ON 28-29 FEB. ENERGETIC
ELECTRON FLUXES SHOULD REMAIN ELEVATED FOR THE NEXT FEW DAYS.
