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 260 Publicado el 2200Z a las 16 Sep 2004IA. Análisis de regiones solares activas y de actividad desde 15-2100Z hasta 16-2100Z Solar activity has been very low. Region 672 (N05W17)
produced a B8.7/Sf at 16/0030 UTC and a B8.4/Sf at 0345 UTC. Region
672 has decayed slightly but has maintained a beta-delta magnetic
configuration. Region 673 (S12E61) is in better view for
observation and, with trailer spots behind a larger lead spot, is in
a beta-gamma configuration. No new regions were numbered today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low.
Regions 672 and 673 may produce C-class flares. Both regions are
capable of isolated M-class flares as well.
IIA. Resumen de la actividad geofísica 15-2100Z a 16-2100Z
The geomagnetic field has been quiet to active. There has been a
slight rise in solar wind speed at ACE since 1600 UTC, to about 550
km/s at the end of the period. The greater than 2 MeV electron flux
at geosynchronous orbit reached high levels today.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be unsettled to active for 17 September, from the
effects of increased solar winds from a geoeffective coronal hole.
Activity should subside for 18-19 September to quiet to unsettled
levels.
