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 256 Publicado el 2200Z a las 12 Sep 2012IA. Análisis de regiones solares activas y de actividad desde 11-2100Z hasta 12-2100Z Solar activity was at low levels. Region 1564 (S13W95)
was the most active sunspot group, producing several C-class flares
as it rotated off the west limb. The largest flare produced was a
long duration C4 at 11/2207Z. Two new B-type Cso regions were
numbered; Region 1570 (S13W34) emerged while 1571 (S12E57) rotated
onto the disk. There was no Earth directed CME activity during the
period.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
with a slight chance for an isolated M-class flare on day 1 (13
September). M-class probability is expected to decrease for the
second and third days (14-15 September) as Region 1564 rotates
further beyond the limb.
IIA. Resumen de la actividad geofísica 11-2100Z a 12-2100Z
Geomagnetic field activity was at mostly quiet levels. There was an
isolated period of major storming at high latitudes during
12/09-12Z. A solar sector boundary crossing was observed at the ACE
spacecraft at about 11/2200Z. 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 quiet with a slight chance for unsettled levels on
days 1 and 2 (13-14 September). An increase to quiet to unsettled
levels with a slight chance for an active period is expected on the
third day (15 September) due to a favorably positioned coronal hole.
