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 18 Dec 2000IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z Solar activity was low. Region 9269 (N11W06) produced
today's largest flare, a C7/Sf at 1111Z. The event was associated
with a relatively slow, full-halo coronal mass ejection as observed
by LASCO imagery. An additional CME occurred, beginning with the
lift-off of a portion of the southern polar crown filament (near
S50E01) at 1824Z. The remainder of today's activity consisted of
numerous C-class events from a variety of regions, including Region
9278 (N09E51) which has rotated more clearly into view as a D-type
sunspot group. New Region 9279 (S11E62) was assigned today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low.
There is a slight chance, however, for an isolated M-class event
from any of regions 9264 (S25W36), 9267 (N08W57), 9276 (S12W85), or
9278 (N09E51).
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
The geomagnetic field was quiet to unsettled during the past 24
hours.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be mostly unsettled for the next two days. An increase
to active, with a possibility for minor storm levels, is expected on
the third day, in response to today's halo CME event.
