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 103 Publicado el 2200Z a las 12 APR 2000IA. Análisis de regiones solares activas y de actividad desde 11-2100Z hasta 12-2100Z SOLAR ACTIVITY REMAINED AT MODERATE LEVELS. REGION 8948
(S16W37) APPEARED TO STABILIZE AS A MODERATE-SIZED, MIXED-POLARITY
REGION FOLLOWING TWO DAYS OF GRADUAL DECAY. IT PRODUCED TWO M-CLASS
FLARES DURING THE PERIOD: AN M1/1N AT 11/2337Z AND AN M1/SF AT
12/0335Z. REGION 8948 ALSO PRODUCED A C2/SN FLARE AT 12/0630Z WITH
AN ASSOCIATED TYPE II RADIO SWEEP. NEW REGION 8959 (S19E29) EMERGED
JUST SOUTH OF REGION 8953 (S16E31).
IB. Pronóstico de la actividad solar
ACTIVITY IS EXPECTED TO BE AT LOW TO
MODERATE LEVELS. THERE IS A FAIR TO GOOD CHANCE FOR ISOLATED M-CLASS
FLARES FROM REGION 8948.
IIA. Resumen de la actividad geofísica 11-2100Z a 12-2100Z
GEOMAGNETIC FIELD ACTIVITY WAS AT QUIET TO UNSETTLED LEVELS. THE
GREATER THAN 2 MEV ELECTRON FLUX AT GEOSYNCHRNOUS ORBIT WAS AT
MODERATE TO HIGH LEVELS.
IIB. Pronóstico de la actividad geofísica
GEOMAGNETIC FIELD ACTIVITY IS
EXPECTED TO REMAIN AT QUIET TO UNSETTLED LEVELS. AT THIS POINT, IT
APPEARS UNLIKELY THAT WE WILL SEE ANY SIGNIFICANT EFFECTS FROM THE
FAINT HALO-CME OBSERVED EARLY ON 10 APRIL. THE GREATER THAN 2 MEV
ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT IS EXPECTED TO DECLINE TO
NORMAL TO MODERATE LEVELS EARLY IN THE PERIOD.
