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 293 Publicado el 2200Z a las 19 Oct 2012IA. Análisis de regiones solares activas y de actividad desde 18-2100Z hasta 19-2100Z Solar Activity was low. Multiple low-level C-class
flares occurred, including a C3 flare at 19/2052Z from an
un-numbered region beyond the southeast limb. Region 1596
(N08E60), an Eko/Beta-Gamma spot group, showed intermediate spot
growth and was the most magnetically complex region on the solar
disk. Several CMEs were observed on LASCO C2 imagery, however, none
are believed to be Earth-directed.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
with a slight chance for an isolated M-class flare during the
forecast period (20-23 October).
IIA. Resumen de la actividad geofísica 18-2100Z a 19-2100Z
The geomagnetic field was quiet over the past 24 hours. Solar wind
speed, as measured at the ACE spacecraft, steadily decreased from
approximately 600 km/s to near 400 km/s. The Bz component of the
interplanetary magnetic field remained mostly positive with maximum
deflections near +/-2 nT. The greater than 2 MeV electron flux at
geosynchronous orbit was at high levels throughout the period.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet on day 1 (20 October). Days 2 and 3 (21-22
October) should see an increase to quiet to unsettled levels due to
the effects of a coronal hole high speed stream.
