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 252 Publicado el 2200Z a las 08 Sep 2012IA. Análisis de regiones solares activas y de actividad desde 07-2100Z hasta 08-2100Z Solar activity was moderate. A long duration M1 flare
was observed at 08/1759Z and appeared to involve an interaction
between Region 1564 (S13W39) and Region 1562 (S21W77). Region 1564
ended the period as the largest on the visible disk, an Eai type
group with beta-gamma magnetic characteristics. A coronal mass
ejection was observed off the west limb in SOHO/LASCO C2 imagery
beginning at 08/10Z. It appeared as a full halo in STEREO-A COR2
imagery. This CME is not expected to be geoeffective.
IB. Pronóstico de la actividad solar
Solar activity is expected to remain
low with a chance for an M-flare on days one and two (09-10
September), decreasing to a slight chance on day three (11
September).
IIA. Resumen de la actividad geofísica 07-2100Z a 08-2100Z
The geomagnetic field ranged from quiet to unsettled levels, with one
period of active conditions observed at high latitudes. The solar
wind speed at the ACE spacecraft remained near 400 km/s throughout
the period. The Bz component of the interplanetary magnetic field
ranged from about +/- 5nT and earth remained in the positive sector.
A slow rise in high energy particles at ACE was observed beginning
around 09/11Z. This rise is believed to be associated with the CME
observed around 09/10Z in coronagraph imagery.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be mostly quiet for the next three days (09-11
September).
