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 220 Publicado el 2200Z a las 08 Aug 2011IA. Análisis de regiones solares activas y de actividad desde 07-2100Z hasta 08-2100Z Solar activity was moderate. Region 1263 (N18W68)
produced the largest x-ray flare of the period, a M3/1b at 1810Z.
This event was accompanied by a Type II radio emission (3284 km/s)
and a Tenflare (300 sfu). STEREO-A COR2 imagery indicated a CME
first visible at 1824Z. Extrapolation from later images suggested a
speed of approximately 2010 km/s. Preliminary LASCO C3 image
analysis suggested a speed of 1152 km/s. Region 1263 ended the
period as a Ekc type spot group with beta-gamma-delta magnetic
characteristics. The remaining regions on the disk were small,
simple and relatively quiet.
IB. Pronóstico de la actividad solar
Solar activity is expected to remain
low to moderate for the next three days (09-11 Aug) with Region 1263
being the most likely source of activity. A slight chance for an
isolated X flare and/or proton event remains through the forecast
period.
IIA. Resumen de la actividad geofísica 07-2100Z a 08-2100Z
The geomagnetic field was quiet to unsettled as the effects from a
recurrent coronal hole high speed stream began to taper off. Solar
wind speed at the ACE spacecraft was approximately 600 km/s while
the Bz component of the interplanetary magnetic field remained near
zero. There was an enhancement of the greater than 10-MeV protons
in response to the M3 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
The geomagnetic field is
expected to be predominantly quiet for the next three days in the
wake of the coronal hole high speed stream. Further analysis of the
CME observed in STEREO and SOHO imagery is underway to determine its
geoeffective potential.
