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 271 Publicado el 2200Z a las 28 Sep 2011IA. Análisis de regiones solares activas y de actividad desde 27-2100Z hasta 28-2100Z Solar activity was moderate. Region 1302 (N13W04)
produced an M1/1n flare at 28/1328Z. Region 1302 also produced a
C9/1n flare at 28/1232Z associated with a 390 sfu Tenflare.
Occasional C-class flares were observed during the period. New
Region 1307 (N14E75) was numbered today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
with a chance for an isolated M- and X-flare from Region 1302.
IIA. Resumen de la actividad geofísica 27-2100Z a 28-2100Z
The geomagnetic field ranged from unsettled to minor storm levels,
due to substorming. The greater than 10 MeV protons at
geosynchronous orbit were enhanced during the period. Wind speeds
reached 548 km/s at 27/2132Z and decreased to approximately 450 km/s
at 28/1716Z.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to unsettled, with isolated active levels at
high latitudes, on day one (29 September). Predominantly quiet
levels are expected on days two and three (30 September-01 October).
