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 051 Publicado el 2200Z a las 20 Feb 2012IA. Análisis de regiones solares activas y de actividad desde 19-2100Z hasta 20-2100Z Solar activity was low. There were three C-class flares
during the past 24 hours. The largest of these was a C4/Sf at 0509Z
from Region 1421 (N18E32). Region 1422 (N16W11) produced the other
two C-flares and is currently the largest group on the disk.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low.
IIA. Resumen de la actividad geofísica 19-2100Z a 20-2100Z
The geomagnetic field was unsettled to active with some isolated
storm periods at high latitudes. Solar wind data from ACE indicated
the influence of a high speed stream from a coronal hole. The
greater than 2 MeV electron flux at geosynchronous orbit reached
high levels during the period.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be unsettled with a chance for active periods on the
first day (21 Feb) due to continued effects from the high speed
stream. A decrease to mostly quiet levels is predicted for the
second day (22 Feb) and quiet levels are expected to continue for
the third day (23 Feb).
