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 052 Publicado el 2200Z a las 21 Feb 2011IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z Solar activity has been low. Region 1161 (N11W42)
produced multiple C-class events and remains an E-type sunspot group
with a beta-gamma magnetic classification, while Region 1162
(N17W46) remained stable and quiet. The periods largest x-ray event
a C7 at 21/1012Z came from Region 1158 which has rotated off the
visible disk.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
to moderate with a slight chance for an X-class event from Region
1161 for the next three days (22-24 February).
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z
The geomagnetic field has been quiet to unsettled during the past 24
hours. Solar wind data from the ACE spacecraft indicated a slight
drop in velocity to around 380 km/s and sustained negative Bz of
-4nT during the period. 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 quiet to unsettled with a slight chance for isolated
active periods during the next three days (22-24 February).
