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 352 Publicado el 2200Z a las 18 Dec 2007IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z Solar activity was at low levels. Region 978 (S08W91)
has produced several C-class events, the largest being a C2 at
18/1320Z.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
very low to low levels. Activity levels should decrease with the
rotation of Region 978 beyond the west limb.
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
The geomagnetic field was at predominately unsettled to active
levels. This elevated activity is due to a coronal hole high speed
stream that has rotated into a geoeffective position. Measurements
at the ACE spacecraft indicated a steady increase in solar wind
speed. At the time of forecast issue the wind speed was
approximately 700 km/s.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at mostly unsettled to active levels for 19 to 21
December due to the continued influence of the high speed stream.
