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
:::::::::: CORRECTED COPY :::::::::: SDF Número 265 Publicado el 2200Z a las 22 Sep 2011IA. Análisis de regiones solares activas y de actividad desde 21-2100Z hasta 22-2100Z Activity was high. New Region 1302 (N11E74) produced a
long-duration X1/2n flare at 22/1101Z. The X1 flare was associated
with Types II and IV radio sweeps, a 970 sfu Tenflare, and a full
halo CME. The CME, already in progress in SOHO LASCO images at
22/1330Z, had an estimated speed of around 1392 km/s. This CME is
not expected to be geoeffective.
IB. Pronóstico de la actividad solar
Solar activity is expected to be high,
with a slight chance for another X-class flare from Region 1302.
IIA. Resumen de la actividad geofísica 21-2100Z a 22-2100Z
The geomagnetic field was quiet.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet on days one and two (23-24 September). Quiet to
unsettled levels, with isolated active levels at high latitudes, are
expected on day three (25 September), due to a weak coronal hole
high-speed stream.
