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 224 Publicado el 2200Z a las 12 Aug 2011IA. Análisis de regiones solares activas y de actividad desde 11-2100Z hasta 12-2100Z Solar activity was very low. Todays largest event was
a B6 at 11/2309Z which appeared to originate from Region 1263 (N17,
L=296, about a day beyond west limb at the time of the event). The
solar disk now consists of only two spotted regions, Region 1269
(S22E03) and Region 1270 (N23E41). Both groups are very small and
only possess spots without penumbra. A filament eruption in the
northeast quadrant and associated CME were observed, beginning at
about 0336Z. The CME appears to be travelling well out of the
ecliptic plane and is not likely to be geoeffective.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low for the next three days.
IIA. Resumen de la actividad geofísica 11-2100Z a 12-2100Z
The geomagnetic field was quiet during the past 24 hours. Solar wind
observations of the Phi angle from the ACE spacecraft appeared to
indicate a transition to a negative polarity sector. The greater
than 2 MeV electron flux at geosynchronous orbit was at high levels
throughout the period.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be predominantly quiet for day 1 (13 August). An
increase to unsettled levels with a chance for active periods is
expected for days 2 and 3 (14-15 August) as a co-rotating
interaction region followed by a negative polarity coronal hole high
speed stream are expected to become weakly geoeffective.
