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 108 Publicado el 2200Z a las 17 Apr 2004IA. Análisis de regiones solares activas y de actividad desde 16-2100Z hasta 17-2100Z Solar activity increased to low levels. A C1 x-ray
flare occurred on the solar southeast limb at 17/1142Z. The source
region for this flare is yet to be numbered due to its location on
the limb. Region 591 (S16W65) continues to decay and was quiescent
throughout the period. Region 595 (S09E55) produced low level
B-class flares early in the period and has since shown decay to the
sunspot area. No new regions were numbered today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
very low to low levels.
IIA. Resumen de la actividad geofísica 16-2100Z a 17-2100Z
The geomagnetic field was at predominantly quiet to unsettled levels.
A period of active conditions occurred between 17/0300 and 0600Z at
the middle latitudes.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at quiet to unsettled levels.
