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 110 Publicado el 2200Z a las 20 Apr 2006 IA. Analysis of Solar Active Regions and Activity from 19/2100Z to 20/2100Z: Solar activity was at very low levels. Region 871 (S06W79) produced a couple B-class flares during the period. Region 874 (S01W11) continues to exhibit steady growth in spot area and magnetic complexity. No new regions were numbered today.IB. Pronóstico de la actividad solar
Solar activity is expected to be at
very low to low levels. Region 874 has a slight chance of producing
an isolated C-class flare.
IIA. Resumen de la actividad geofísica 19-2100Z a 20-2100Z
The geomagnetic field was at quiet levels. The greater than 2 MeV
electron flux at geosynchronous orbit reached high levels again
today.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at quiet to unsettled levels. A weak recurrent
coronal hole may lead to isolated active periods on 23 April.
