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 116 Publicado el 2200Z a las 26 Apr 2005IA. Análisis de regiones solares activas y de actividad desde 25-2100Z hasta 26-2100Z Solar activity increased to low levels today. Region
756 (S06E55) appears to be a magnetically complex beta-delta sunspot
group. There were several C-class flares produced from this region
during the period, the largest was an impulsive C5 x-ray event that
occurred at 26/0441Z. A disappearing filament was observed starting
late yesterday and continued into the early part of the interval.
This event resulted in a partial halo CME which was first observed
in SOHO/LASCO C2 imagery beginning at 24/2306Z. There is a chance
this CME may become geoeffective and produce a weak glancing blow as
it passes the Earth. No new regions were numbered today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
low levels. There is a slight chance for an isolated M-class flare
from Region 756.
IIA. Resumen de la actividad geofísica 25-2100Z a 26-2100Z
The geomagnetic field was at quiet levels today.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at predominantly quiet to unsettled levels. The
partial halo CME seen today on the southwest limb may result in
isolated periods of active conditions on 29 April.
