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 2011IA. Análisis de regiones solares activas y de actividad desde 06-2100Z hasta 07-2100Z Solar activity was high. Region 1283 (N14W32) produced
another major flare, an X2/2b at 06/2220Z. The X2 flare was
associated with Types II and IV radio sweeps, a 740 sfu Tenflare and
an Earth-directed halo CME. The CME had an estimated speed of around
800 km/s, based on STEREO-A COR2 images, with the bulk of mass
directed north of the ecliptic plane. Region 1283 maintained a weak
magnetic delta in the north-central portion of the group and was
classified as a Dai-type with a beta-gamma-delta magnetic
configuration. No new regions were numbered.
IB. Pronóstico de la actividad solar
Solar activity is expected to be
moderate during the period (08 - 10 September) with a chance for
another X-class flare from Region 1283.
IIA. Resumen de la actividad geofísica 06-2100Z a 07-2100Z
Geomagnetic field activity was at mostly quiet levels. A proton flux
enhancement at greater than 100 MeV and greater than 10 MeV began
around 06/2300Z at geosynchronous orbit in the wake of the X2 flare
mentioned above. The greater than 2 MeV electron flux at
geosynchronous orbit reached high levels during the period.
IIB. Pronóstico de la actividad geofísica
Geomagnetic activity is
expected to be at mostly quiet levels on day 1 (08 September). An
increase to unsettled levels, with a chance for active levels, is
expected late on day 2 (09 September) due to a CME arrival. A
further increase to unsettled to active levels, with a chance for
minor storm levels, is expected on day 3 (10 September) as the CME
passage continues. There will be a chance for a greater than 10 MeV
proton event at geosynchronous orbit during the period.
