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 054 Publicado el 2200Z a las 23 Feb 2012IA. Análisis de regiones solares activas y de actividad desde 22-2100Z hasta 23-2100Z Solar activity was very low. Region 1422 (N15W52)
showed decay in its trailing spots. A new region appeared on the NE
limb and was numbered Region 1423 (N18E70). Two CMEs were observed
overnight; the first off the North limb, observed in LASCO C2
imagery beginning at approximately 23/0148Z and the second beginning
at 23/0824Z off the NW limb. The second CME was associated with a
filament eruption on the NW limb first seen in SDO/AIA 193 imagery
at 23/0746Z. None of the CMEs are expected to be geoeffective.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
very low levels with a chance for a C-class activity.
IIA. Resumen de la actividad geofísica 22-2100Z a 23-2100Z
The geomagnetic field was quiet. Solar wind speed at the ACE
spacecraft decreased from approximately 530 km/s to 440 km/s while
the Bz component of the Interplanetary Magnetic Field did not vary
much beyond +/- 4 nT.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to continue at mostly quiet conditions for the forecast
period (24 - 26 February).
