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 360 Publicado el 2200Z a las 26 Dec 2002IA. Análisis de regiones solares activas y de actividad desde 25-2100Z hasta 26-2100Z Solar Activity has been low during the past 24 hours.
Today's flare activity consisted of a few low-level C-class
subflares. A backward C-shaped filament erupted off the disk at
about 1805 UTC today. The filament eruption was associated with a
fast, narrow CME off the northeast limb, first seen in the C2 field
of view at 1854 UTC. The estimated CME velocity in C2 was about 715
km/s.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
for the next three days.
IIA. Resumen de la actividad geofísica 25-2100Z a 26-2100Z
The geomagnetic field ranged from quiet to active levels. Solar wind
data seem to indicate the onset of a high speed coronal hole wind
stream around 1600 UTC, with speeds up to about 500 km/s.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be mostly active for the next two days in response to
the high speed solar wind stream associated with a 30 degree wide
solar coronal hole. Conditions should subside slightly to unsettled
to active levels by the third day.
