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 219 Publicado el 2200Z a las 07 Aug 2003IA. Análisis de regiones solares activas y de actividad desde 06-2100Z hasta 07-2100Z Solar activity has been low. Region 421 (S07W72)
produced several flares, including a C1.3 at 07/1203 UTC. Two
C-class flares were produced from an active region just on the other
side of the east limb, the largest a C2.1 at 07/2050 UTC. These
events were optically correlated with SXI imagery. Region 424 has
stabilized in size and magnetic complexity. New Region 430 (S08W13)
was numbered today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
low to moderate levels. C-class flares are possible from Region
421. In the next few days, active regions just beyond the east limb
should begin to appear earthside, which may produce increased solar
activity.
IIA. Resumen de la actividad geofísica 06-2100Z a 07-2100Z
The geomagnetic field has been at quiet to active levels. High
solar wind speeds (up to 700 km/s), associated with a coronal hole in
geoeffective position, are the likely cause of active conditions late
in the period.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at quiet to active levels, with isolated minor storm
conditions possible, for day one, due to continued influence of an
equatorial coronal hole. On days two and three, as the coronal hole
rotates out of geoeffective position, activity should decrease to
quiet to unsettled conditions.
