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 051 Publicado el 2200Z a las 20 Feb 2003IA. Análisis de regiones solares activas y de actividad desde 19-2100Z hasta 20-2100Z Solar activity was low. Only a few C-class events
occurred during the day. Region 290 (N17E18) grew in both white
light and H-alpha as it produced occasional subflares. Little else
of significance occurred.
IB. Pronóstico de la actividad solar
Solar activity is expected to remain
low.
IIA. Resumen de la actividad geofísica 19-2100Z a 20-2100Z
The geomagnetic field was at quiet to active levels. The solar wind
is currently hovering near 700 km/s, emanating from a coronal hole
in the western hemisphere.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at unsettled to active levels for the next 24 hours.
Conditions should calm to strictly unsettled levels by the end of
the period.
