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 2004IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z Solar activity has been very low. Region 713 (S08E22)
has produced several B-class flares and retains its beta-gamma
magnetic configuration.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low to low. There is a chance for an isolated C-class event from
Region 713.
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z
The geomagnetic field was quiet to unsettled with an isolated period
of active to minor storm conditions observed at 21/1200 UTC. Solar
wind data indicated a possible co-rotating interaction region
signature during this period. Solar wind speed ranged from around
350 to 490 km/s with the IMF Bz fluctuating to -14 nT.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be predominately quiet to unsettled with isolated
periods of active conditions on 22-23 December due to coronal hole
effects. Quiet to unsettled conditions are expected for 24
December.
