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 221 Publicado el 2200Z a las 08 Aug 2012IA. Análisis de regiones solares activas y de actividad desde 07-2100Z hasta 08-2100Z Solar activity was low. Region 1542 (S14E50) remained
the most active region on the solar disk, producing seven C-class
flares. The largest of these flares was a C4/Sf flare that occurred
at 08/1132Z. A large portion of a filament erupted from the
southwest quadrant beginning around 08/0200Z. A slow coronal mass
ejection (CME) (estimated plane-of-sky speed 346 km/s) was first
observed off the west limb in SOHO/LASCO C2 imagery at 08/0612Z and
was likely associated with the filament eruption. The bulk of the
CME material did not appear to be Earth-directed.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
with a slight chance for an isolated M-class flare.
IIA. Resumen de la actividad geofísica 07-2100Z a 08-2100Z
The geomagnetic field was quiet to unsettled with an active period
from 08/0000-0300Z. Indications of a solar sector boundary crossing
were evident on the ACE spacecraft as sustained southward IMF Bz and
enhanced IMF Bt occurred prior to the active period. ACE EPAM data
indicated the beginning of a slow rise in energetic particles at
approximately 08/1200Z. This rise is likely associated with the
anticipated glancing blow from the 04 Aug CME.
IIB. Pronóstico de la actividad geofísica
Geomagnetic activity is
expected to be quiet to unsettled with a slight chance for isolated
active to minor storm periods early on day one (09 Aug). Activity
should return to quiet to unsettled late in the day as effects of
the CME wane. Days two and three (10 and 11 Aug) are expected to be
at predominately quiet levels.
