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 351 Publicado el 2200Z a las 17 Dec 2007IA. Análisis de regiones solares activas y de actividad desde 16-2100Z hasta 17-2100Z Solar activity was low. Region 978 (S10W78) produced
today's only C-class event, a C2 at 0716Z. The region appears to be
decaying as it approaches west limb.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low, although there continues to be a chance for an isolated C-class
event.
IIA. Resumen de la actividad geofísica 16-2100Z a 17-2100Z
The geomagnetic field ranged from quiet to minor storm levels. The
field was initially quiet but became disturbed after a sudden
impulse was observed at 0300Z. The sudden impulse was preceded by a
weak shock in the solar wind observed at ACE at 0204Z. The shock was
followed by an increase in velocity and magnetic field at ACE
consistent with a corotating interaction region which was then
followed by a high speed stream. Active to minor storm conditions
prevailed from 0600-1200Z, followed by mostly active conditions. As
of forecast issue time the solar wind velocity remains elevated with
values around 550-600 km/s.
IIB. Pronóstico de la actividad geofísica
Geomagnetic activity is
expected to be unsettled to active for the next three days (18-20
December), due to continued influence of the high speed stream.
