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 301 Publicado el 2200Z a las 27 Oct 2012IA. Análisis de regiones solares activas y de actividad desde 26-2100Z hasta 27-2100Z Solar activity was low. Three low-level C-class flares
were observed from behind the west limb, likely from old Region 1594
(S27, L=200). Region 1598 (S11W10), a Dkc/Beta-Delta spot group,
remained the most magnetically complex region on the visible disk
and produced a B9/Sf flare at 27/1235Z. Region 1596 (N08W48), a
Dao/Beta-Gamma spot group, has shown signs of penumbral decay,
mainly in its trailer spots. The remaining two spot groups were
stable and unremarkable. A CME was observed in STEREO Ahead COR 2
imagery at 27/1824Z. Further analysis will be performed to
determine its geo-effectiveness as data becomes available.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
with a slight chance for isolated M-class flares for the next three
days (28-30 October).
IIA. Resumen de la actividad geofísica 26-2100Z a 27-2100Z
The geomagnetic field has been quiet for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, remained steady at
approximately 350 km/s. The Bz component of the interplanetary
magnetic field had minor deflections of +/- 5 nT while the total
field remained steady at 5 nT. 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 remain quiet for the next three days (28-30 October).
