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 354 Publicado el 2200Z a las 20 Dec 2001IA. Análisis de regiones solares activas y de actividad desde 19-2100Z hasta 20-2100Z Solar activity was low. Region 9742 (N10E13) produced
several C-class events including a C8 flare at 20/0438Z. This region
exhibited impressive flux emergence and spot growth this period,
almost doubling in size and spot count. Most growth was concentrated
in the trailer portions of the region, but mixed polarities were
obvious throughout the spot group. Regions 9741 (N05W21) and 9747
(N12E58) produced occasional minor C-class flares. Moderately
complex Regions 9733 (N12W88) and 9739 (S14W90) are rotating quietly
around the west limb. A large prominence eruption and associated CME
occurred on the SE limb between 19/2344 - 20/0028Z. New Regions 9748
(S11E36), and 9749 (S08E72) were numbered today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
moderate levels. Region 9742 holds good potential for M-class
activity and is developing potential for a major flare.
IIA. Resumen de la actividad geofísica 19-2100Z a 20-2100Z
The geomagnetic field was quiet.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to unsettled. Periods of unsettled conditions
are likely on days two and three as a large southern coronal hole
moves into a geoeffectively favorable position.
