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 250 Publicado el 2200Z a las 07 Sep 2003IA. Análisis de regiones solares activas y de actividad desde 06-2100Z hasta 07-2100Z Solar activity was low. A long-duration C5 flare
occurred at 07/1407Z in Region 450 (S17W63). This flare was
characterized in H-alpha imagery by several prolonged bright kernels
in ribbon form along a thin NW-SE filament. This event appeared to
trigger a large 19 degree filament eruption near S38W18. Minor
centimetric radio bursts also accompanied this event, and LASCO
imagery revealed a large CME in progress. The X-ray flux was still
considerably enhanced by the end of the period. Region 450 is a
small, simple beta group in decay. The remaining active regions
were either stable or in decay.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
to very low. The current X-ray flux levels are elevated following
today's eruption, but are expected to return to the pre-flare
background level early in the period. Very isolated low C-class
flares are possible.
IIA. Resumen de la actividad geofísica 06-2100Z a 07-2100Z
The geomagnetic field was quiet to unsettled. Solar wind speed has
declined to below 450 km/s. The greater than 2 MeV electron flux at
geosynchronous orbit was at high levels.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to continue at quiet to unsettled levels through day one. A
recurring high speed coronal hole stream will likely produce active
to minor storm periods on days two and three. Activity on day three
may be further enhanced by transient material from today's CME off
the SW limb.
