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 292 Publicado el 2200Z a las 18 Oct 2012IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z Solar activity was very low. The x-ray background
remained steady at B4 for the duration of the period. Newly
numbered Region 1596 (N11E73) is a ~300 millionths E-type group and
is the most prominent region on the disk. New Region 1597 (S21W30)
emerged as a small bi-polar region. The other regions on the disk
were stable or decaying.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
with a slight chance for an isolated M-class event during the next
three days (19 - 21 Oct).
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
The geomagnetic field was quiet during the past 24 hours. The solar
wind speed measured at the ACE spacecraft gradually increased from
around 500 km/s to the end-of-day value around 600 km/s. These
signatures are consistent with a high speed stream from a negative
polarity coronal hole. 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 with a chance for an isolated unsettled period
for the next two days (19 - 20 Oct). The geomagnetic field is
expected to be mostly unsettled on 21 Oct due to a high speed stream
associated with a negative polarity coronal hole.
