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 352 Publicado el 2200Z a las 18 Dec 2001IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z Solar activity was at low levels. Only isolated C-class
events were observed during the period. Three regions have
moderately complex beta-gamma magnetic classification: 9733
(N13W62), 9738 (S18W12), and 9742 (N10E37). Regions 9738 and 9742
are showing signs of increased activity and growth, while 9733 is
steadily decaying. Region 9733 will rotate over the west limb on 21
December. One new region was numbered: 9745 (N18E60).
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
low to moderate levels. Regions 9738 and 9742 are expected to
continue to grow in size and complexity and should produce increased
levels of activity. Region 9733 continues to retain a slight chance
of producing a major flare before it transits over the western limb.
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
The geomagnetic field was at quiet to unsettled conditions.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to continue to be at quiet to unsettled levels.
