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 333 Publicado el 2200Z a las 28 Nov 2012IA. Análisis de regiones solares activas y de actividad desde 27-2100Z hasta 28-2100Z Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M1 event observed at
27/2126Z from Region 1620 (S12W57). The region continued to grow in
areal coverage and maintained a beta-gamma-delta configuration. Region
1623 (N09E60) also grew significantly in areal coverage but the magnetic
complexity is difficult to determine with its proximity to the limb.
There are currently 4 numbered sunspot regions on the disk. No
Earth-directed CMEs were observed during the period.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at low to
moderate levels on days one, two, and three (29 Nov, 30 Nov, 01 Dec).
IIA. Resumen de la actividad geofísica 27-2100Z a 28-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 448 km/s at
28/0119Z and has since decreased to nominal levels.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to remain quiet through the majority of 29 Nov. Quiet to unsettled
conditions with a chance for active periods are expected to begin late
on day one (around 29/1800Z) with the anticipated arrival of the 26 and
27 Nov CMEs. Activity is expected to return to mostly quiet levels by
the latter half of day two (30 Nov) as the effects from the CMEs
subside. Isolated unsettled periods are possible through day three (01
Dec) due to coronal hole high speed stream effects.
