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 330 Publicado el 2200Z a las 26 NOV 1999IA. Análisis de regiones solares activas y de actividad desde 25-2100Z hasta 26-2100Z SOLAR ACTIVITY WAS HIGH. REGION 8771 (S14W63) PRODUCED
AN M6/2N FLARE AT 26/1343Z. THIS MAGNETICALLY COMPLEX REGION WAS
ALSO RESPONSIBLE FOR AN M5/3B TENFLARE AT 26/0123Z AND AN M1/2B
FLARE AT 26/0400Z. THOUGH THERE WERE SOME INDICATIONS OF DECAY, THE
DELTA CONFIGURATION REMAINS INTACT. A PARTIAL HALO CORONAL MASS
EJECTION WAS OBSERVED MOSTLY OFF THE WEST LIMB AT 26/0754Z. IT IS
DIFFICULT TO DETERMINE THE SOURCE FOR THE CME, BUT A C3/SF WITH A
TYPE II SWEEP WAS OBSERVED IN REGION 8778 (S14W05) AT 26/0705Z. THIS
REGION DID EXHIBIT SOME GROWTH THIS PERIOD AND REMAINS A MODERATELY
COMPLEX E-TYPE SPOT GROUP. REMAINING REGIONS WERE MOSTLY QUIET.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO REMAIN
AT MODERATE TO HIGH LEVELS. EXPECT MORE M-CLASS ACTIVITY FROM REGION
8771 WITH A CHANCE FOR ANOTHER MAJOR FLARE. REGION 8778 IS EXPECTED
TO CONTINUE PRODUCING C-CLASS EVENTS WITH AN INCREASING CHANCE FOR
AN ISOLATED M-CLASS.
IIA. Resumen de la actividad geofísica 25-2100Z a 26-2100Z
THE GEOMAGNETIC FIELD WAS QUIET.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO REMAIN QUIET FOR DAY ONE AND TWO. EFFECTS FROM TODAY'S
CME MAY PRODUCE ACTIVE CONDITIONS ON DAY THREE.
