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 17 Dec 2004IA. Análisis de regiones solares activas y de actividad desde 16-2100Z hasta 17-2100Z Solar activity was very low. Region 710 (S07W72) has
shown a slight increase in area and spot number, but remains quiet.
New regions 712 (S10E50) and 713 (S10E70) were numbered today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low to low. There is a chance for a C-class flare from the new
regions near the southeast limb.
IIA. Resumen de la actividad geofísica 16-2100Z a 17-2100Z
The geomagnetic field was at quiet to active levels with a period of
minor storming between 17/0300Z and 17/0600Z. The active to minor
storm levels were due to the continued influence of a geoeffective
coronal hole high speed stream. There was an increase in the solar
wind speed at ACE from approximately 550 km/s to 650 km/s during the
reporting period.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to active with minor storm periods possible at
high latitudes on 18 December. Expect quiet to unsettled with
isolated active conditions on 19 December as the high speed coronal
hole stream subsides. Expect quiet to unsettled levels on 20
December.
