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 355 Publicado el 2200Z a las 21 Dec 2001IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z Solar activity was low. Region 9742 (N10W03) is the
largest and most active group on the visible disk and produced
several minor C-class flares. This beta-gamma region continues to
grow in spot count, area, and magnetic complexity, and now exceeds
700 millionths of white light area. No remarkable activity or
developments were observed in the remaining active regions. New
Regions 9750 (S16W64) and 9751 (N04E68) were numbered today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be
moderate. Region 9742 has good potential for M-class flares and an
isolated chance for a major flare.
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z
The geomagnetic field was quiet to active. An increase in the solar
wind speed began at around 21/1100Z. This increase was accompanied
by sustained periods of southward Bz resulting in unsettled to
active periods at all latitudes.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to continue at quiet to active levels.
