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 362 Publicado el 2200Z a las 27 Dec 2000IA. Análisis de regiones solares activas y de actividad desde 26-2100Z hasta 27-2100Z Solar activity was at moderate levels. Region 9289
(S08E64) produced an M4/1f at 27/1544 UTC. This region also
produced several mid-level C-class flares throughout the day, as did
Region 9283 (S11E11), which is now exhibiting a somewhat more
complex magnetic configuration that may indicate emergence of two
bipolar subgroups in close proximity within the active region.
Meanwhile, Region 9280 (N10W31) has diminished in activity, areal
coverage and spot count, and Region 9289 has replaced it as the
largest group on the disk (330 millionths, in a Dao-beta
configuration). Other activity observed this period included a weak
Type II radio sweep at 27/0347 UTC. SOHO/LASCO imagery suggests the
source to be a CME event from behind the west limb, which does not
appear earth-directed. New Region 9290 (N30E31) was numbered today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
to moderate. A somewhat increased chance for isolated M-class
activity is expected for regions 9283 and 9289.
IIA. Resumen de la actividad geofísica 26-2100Z a 27-2100Z
The geomagnetic field has been at quiet to unsettled levels.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to unsettled for the next three days, barring
an earth-directed CME event.
