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 363 Publicado el 2200Z a las 28 Dec 2000IA. Análisis de regiones solares activas y de actividad desde 27-2100Z hasta 28-2100Z Solar activity was low. Several, mostly small C-class
flares were observed. Region 9289 (S06E57) has evolved quickly into
the largest and most complex region on the visible disk. It now
exhibits an "Eko" beta-gamma spot group nearing 800 millionths of
white light area, and was responsible for most of the C-class
flares. Region 9279 (S12W77) produced a C2/sf flare at 28/1429Z with
an associated Type II sweep. Region 9283 (S11W03) also produced
isolated C-class flares, the largest being a C5/sf at 27/2218Z.
Perhaps the most impressive event of the period was a large, full
halo CME on LASCO imagery at 28/1230Z. There was no optical
correlation of the source - the event appears to have originated
from the backside of the disk.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
to moderate. Region 9289 has potential for isolated M-class flares.
IIA. Resumen de la actividad geofísica 27-2100Z a 28-2100Z
The geomagnetic field was mostly quiet with isolated unsettled
conditions at high latitudes.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to continue at quiet to unsettled levels.
