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 296 Publicado el 2200Z a las 22 Oct 2004IA. Análisis de regiones solares activas y de actividad desde 21-2100Z hasta 22-2100Z Solar activity increased to moderate levels today.
Region 687 (N10E39) produced an M2/1n flare at 22/0811Z that had an
associated Type IV radio sweep and a Type II radio sweep with an
estimated shock velocity 521 km/sec. LASCO imagery depicted a CME
shortly following this event which may have a weak Earth-bound
component. The sunspot area in this region underwent strong growth
during the period, adding penumbral coverage to the trailing cluster
of spots in the group. Region 682 (S13W59) underwent little change
today and produced a single low level B-class flare. Region 684
(S05E01) has shown rapid growth in sunspot area and magnetic
structure during the period. Region 690 (N00E78) was numbered
today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
low to moderate levels. Region 687 is capable of producing further
M-class flares and has a slight chance of producing an isolated
major flare.
IIA. Resumen de la actividad geofísica 21-2100Z a 22-2100Z
The geomagnetic field was at quiet levels today.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at quiet to unsettled levels on 23 and 24 October. A
chance of isolated active conditions may occur on 25 October due to
the potential for a glancing blow from the CME that resulted from
the M2/1n flare mentioned in IA.
