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 260 Publicado el 2200Z a las 16 Sep 2012IA. Análisis de regiones solares activas y de actividad desde 15-2100Z hasta 16-2100Z Solar activity was very low. New Region 1573 (N17E62 -
Axx/alpha) produced occasional B-class flares as it rotated into
view. Region 1566 (N23W89 - Hrx/alpha) produced a B-class flare as
it approached the west limb. Region 1569 (S12W13 - Cso/beta) showed
gradual spot and penumbral decay in its intermediate and trailer
portions. New Region 1574 (S25W15 - Bxo/beta), a small
reverse-polarity group, was also numbered. No Earth-directed CME activity
occurred during the period.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low through the period (17 - 19 September) with a chance for a
C-class flare.
IIA. Resumen de la actividad geofísica 15-2100Z a 16-2100Z
Geomagnetic field activity was at quiet to unsettled levels. An
increase to unsettled levels occurred late in the period associated
with the onset of a solar sector boundary crossing (SSBC).
Intermittent periods of weakly-southward IMF Bz along with minor
increases in solar wind speeds and IMF Bt were associated with the
SSBC.
IIB. Pronóstico de la actividad geofísica
Geomagnetic field activity is
expected to remain at quiet to unsettled levels on day 1 (17
September) due to minor changes in the solar wind. A decrease to
quiet levels is expected on day 2 (18 September). Activity is
expected to increase to quiet to unsettled levels on day 3 (19
September), with a slight chance for active levels, as a coronal
hole high-speed stream begins to disturb the field.
