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 118 Publicado el 2200Z a las 27 Apr 2004IA. Análisis de regiones solares activas y de actividad desde 26-2100Z hasta 27-2100Z Solar activity has been low. Region 599 (N14E02)
produced a C3.1 flare at 27/0723 UTC with an associated Type II
flare with a speed of 732 km/s. LASCO imagery was not available, but
EIT imagery indicated significant dimming in the area of Region 599,
suggesting the existence of a CME. No significant development was
observed on regions on the visible disk, and no new regions were
numbered.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low to low. Region 599 has the potential to produce C- and isolated
M-class flares.
IIA. Resumen de la actividad geofísica 26-2100Z a 27-2100Z
The geomagnetic field has been quiet to unsettled.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to unsettled, with isolated active or minor
storm conditions possible on day three (30 April) from a CME
associated with the C3 flare observed today.
