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 353 Publicado el 2200Z a las 19 Dec 2001IA. Análisis de regiones solares activas y de actividad desde 18-2100Z hasta 19-2100Z Solar activity was moderate. Region 9739 (S14W82)
produced occasional C-class events and the single M-class flare of
the period, an M1/Sf at 19/1706Z. This region has been growing
steadily since appearing on the disk on 13 Dec and now exceeds 400
millionths of white light area as it rotates around the west limb.
Region 9733 (N13W75) continues to produce minor C-class events as
it approaches the west limb. Region 9742 (N12E27) maintains moderate
magnetic complexity and size, and produced a C4 flare at 19/0232Z).
New Regions 9746 (S18E08) and 9747 (N12E71) were numbered today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
to moderate. Regions 9733 and 9739 have potential to produce an
M-class flare on the west limb. Region 9742 also has a slim chance
of producing an M-class flare.
IIA. Resumen de la actividad geofísica 18-2100Z a 19-2100Z
The geomagnetic field was quiet to unsettled. The IMF Bz was mostly
southward this period creating prolonged disturbed periods.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to continue at quiet to unsettled levels. Unsettled
conditions are likely on days two and three as a southern coronal
hole moves into a geoeffectively favorable position.
