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 233 Publicado el 2200Z a las 21 Aug 2011IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z Solar activity was very low to low. Region 1271
(N16W01) produced a C2/Sf event at 20/2258Z. Region 1272 (S21E03)
produced several B-class/Sf events in the past 24 hours followed by
a C1/Sf at 21/1840Z. Regions 1271 and 1272 showed significant growth
in trailer areas. Region 1275 (N06E68) was numbered today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
with a slight chance for moderate activity.
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z
The geomagnetic field was quiet to unsettled due to the arrival of a
favorably positioned negative polarity coronal hole.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be unsettled with a chance for active conditions at high
latitudes on Days 1 and 2 (22-23 Aug) with the arrival of a second
coronal hole high speed stream (HSS). Day 3 (24 Aug) is expected to
decrease to quiet conditions as effects from the HSS subside.
