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 328 Publicado el 2200Z a las 23 Nov 2012IA. Análisis de regiones solares activas y de actividad desde 22-2100Z hasta 23-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C1 event observed at
23/1212Z from Region 1618 (N08W27). Although this region retained its
beta-gamma-delta magnetic characteristics, it experienced intermediate
penumbral decay. All other regions on the disk remained stable and
quiet. Between 1200 and 1300Z, a 29 degree filament was observed in SDO
AIA 304 imagery lifting off from the southeast limb. The subsequent CME
was observed in STEREO-A and B COR2 imagery beginning around 1400Z.
Using geometric localization, a preliminary speed of approximately 550
km/s was obtained. This suggests an arrival at earth early on 27
November.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at low
levels, with a slight chance for moderate activity, for the entire
forecast period (24-26 Nov).
IIA. Resumen de la actividad geofísica 22-2100Z a 23-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
at the ACE spacecraft reached 389km/s at 23/2117Z. Total IMF reached 12
nT at 23/2116Z. The maximum southward component of Bz was -8.8 nT at
23/2112Z. These values coincided with the arrival of an interplanetary
shock at ACE around 23/2112Z from the 20 Nov CME. The greater than 2
MeV electron flux at geosynchronous orbit reached a maximum of 1408 pfu.
IIB. Pronóstico de la actividad geofísica
Geomagnetic field activity is
expected to begin at active levels and reach major storm levels early on
day one (24 Nov) with the effects from the 20 Nov CME coupled with the
anticipated arrival of the 21 Nov CME. On day two (25 Nov), conditions
are expected to return to unsettled to active levels due to residual CME
effects combined with a coronal hole high speed stream. The unsettled
levels may persist into day three (26 November).
