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 356 Publicado el 2200Z a las 21 Dec 2008IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z Solar activity was very low. The visible disk remained
spotless. Please note: the observed Penticton 10.7 cm flux of 69 is
estimated today.
IB. Pronóstico de la actividad solar
Solar activity is expected to remain
at very low levels.
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z
The geomagnetic field was at quiet levels.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to unsettled on 22 - 23 December. A recurrent
coronal hole high speed stream is expected to rotate into a
geoeffective position on 22 December and affect the field through
the 23rd. Mostly quiet conditions are expected by 24 December.
