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 117 Publicado el 2200Z a las 27 Apr 2011IA. Análisis de regiones solares activas y de actividad desde 26-2100Z hasta 27-2100Z Solar activity has been at low levels for the past 24
hours. New Region 1201 (N16E40), grew rapidly early in the period,
producing a C2 flare at 27/0301Z with a non-Earth directed CME. A
Type II radio sweep, with a shock velocity of 845 km/s, was also
associated with this event. Region 1201 has since decayed and is
now spotless plage. A second, back-sided CME, first visible in
LASCO C2 imagery at 27/0800Z, was also observed during the period.
Neither CME is expected to become geoeffective. Region 1199 (N21W34)
continues to grow and evolve.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
very low to low levels for the next three days (28-30 April).
IIA. Resumen de la actividad geofísica 26-2100Z a 27-2100Z
The geomagnetic field has been at quiet levels for the past 24 hours.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at predominantly quiet levels for the next 2 days
(28-29 April). Unsettled to active levels are expected on day three
(30 April) as a recurrent coronal hole high-speed stream becomes
geoeffective.
