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 326 Publicado el 2200Z a las 22 NOV 1999IA. Análisis de regiones solares activas y de actividad desde 21-2100Z hasta 22-2100Z SOLAR ACTIVITY DECREASED TO LOW LEVELS. REGION 8765
(S13W72) SHOWED GRADUAL DECAY AS IT APPROACHED THE WEST LIMB, BUT
REMAINED LARGE AND MAGNETICALLY COMPLEX. IT PRODUCED ISOLATED
SUBFLARES DURING THE PERIOD INCLUDING A C8/SF AT 22/1217Z. REGION
8771 (S16W11) ALSO PRODUCED ISOLATED SUBFLARES. IT SHOWED GRADUAL
GROWTH AND REMAINED MODERATE IN SIZE AND MAGNETIC COMPLEXITY. REGION
8776 (S29W01) GREW GRADUALLY AND PRODUCED ISOLATED SUBFLARES, BUT
REMAINED A SIMPLY-STRUCTURED BIPOLE. REGION 8766 (N17W49) CONTINUED
TO SLOWLY DECAY. NO NEW REGIONS WERE ASSIGNED.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE
MODERATE. REGIONS 8765 AND 8771 COULD PRODUCE ISOLATED M-CLASS
FLARES. THERE IS ALSO A SLIGHT CHANCE FOR AN ISOLATED MAJOR FLARE
FROM EITHER OF THESE REGIONS.
IIA. Resumen de la actividad geofísica 21-2100Z a 22-2100Z
GEOMAGNETIC FIELD ACTIVITY RANGED FROM QUIET TO ACTIVE LEVELS. ACTIVE
LEVELS OCCURRED DURING 22/1100 - 1400Z IN RESPONSE TO A PERIOD OF
SUSTAINED SOUTHWARD IMF BZ. THE GREATER THAN 2 MEV ELECTRON FLUX
DECLINED TO NORMAL TO MODERATE LEVELS.
IIB. Pronóstico de la actividad geofísica
GEOMAGNETIC FIELD ACTIVITY IS
EXPECTED TO BE AT QUIET TO (BRIEFLY) ACTIVE LEVELS DURING THE FIRST
DAY DUE TO CORONAL HOLE EFFECTS. QUIET TO UNSETTLED LEVELS ARE
EXPECTED DURING THE REMAINDER OF THE PERIOD. THERE IS A SLIGHT
CHANCE FOR A PROTON EVENT AT GEOSYNCHRONOUS ORBIT, SHOULD A MAJOR
FLARE OCCUR FROM REGIONS 8765 OR 8771.
