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 335 Publicado el 2200Z a las 30 Nov 2012IA. Análisis de regiones solares activas y de actividad desde 29-2100Z hasta 30-2100Z Solar activity was low. Region 1625 (N14E36, Dao/beta-gamma)
remained the most flare-productive region with frequent low-level
C-class subflares. It showed some intermediate spot decay during the
period, but retained its beta-gamma magnetic configuration. Region 1620
(S13W81, Eai/beta-gamma) produced the largest flare of the period: a C5
at 30/1748 UTC as it approached the west limb. No significant changes
were noted in the region, but analysis was hampered due to limb
proximity. No significant changes were noted in Region 1623 (N08E35,
Dao/beta-gamma). There are currently 4 numbered sunspot regions on the
disk. No Earth-directed CME activity occurred during the period.
IB. Pronóstico de la actividad solar
Activity is expected to be low through 03
December with a slight chance for an isolated M-class flare. At present,
Regions 1620 and 1625 appear to be the most capable of producing
isolated M-class activity.
IIA. Resumen de la actividad geofísica 29-2100Z a 30-2100Z
Geomagnetic
field activity was at quiet levels with no sign of the CME passage that
was expected to begin around 30/0000 UTC. Solar winds were low in the
approximate 326 to 363 km/s range. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 103 pfu.
IIB. Pronóstico de la actividad geofísica
Geomagnetic field activity is
expected to increase to quiet to unsettled levels on 01 December with a
slight chance for active levels due to CH HSS effects. Activity is
expected to decrease to mostly quiet levels during 02 - 03 December as
the CH HSS subsides.
