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
:::::::::: CORRECTED COPY :::::::::: SDF Número 331 Publicado el 2200Z a las 27 Nov 2011IA. Análisis de regiones solares activas y de actividad desde 26-2100Z hasta 27-2100Z Solar activity has been at low levels for the past 24
hours. Region 1354 (S16W64) decayed to plage late yesterday, however
early in the period today, a CME originated from the vicinity of
Region 1354. This CME was first visible in LASCO C2 imagery at
27/1036Z and appears to have no Earth directed components. At the
time of this report, an Eruptive Prominence on the Limb (EPL) was
recorded off the west limb around Region 1353 (N08W62). Early
analysis also indicates this CME not being Earth directed. New
Region 1362 (N08E76) was numbered today as it rotated onto the east
limb.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
low levels with a slight chance for M-class activity for the next
three days (28-30 November).
IIA. Resumen de la actividad geofísica 26-2100Z a 27-2100Z
The geomagnetic field has been at predominantly quiet levels with an
isolated period at active levels recorded at high latitudes. Solar
wind measurements, as made by the ACE spacecraft, indicate the
possible arrival of the corotating interaction region (CIR) in front
of the anticipated coronal hole high speed stream (CH HSS). The
greater than 10 MeV proton event that began yesterday at 1125Z is
still in progress. Max flux for this event, so far, was 80 pfu at
27/0125Z.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at unsettled to active levels with a chance for minor
storm periods for the next two days (28-29 November). These elevated
levels are expected due to the combination of the arrival of a CH
HSS and CME effects. On day three (30 November), a slight decrease
in activity to mostly unsettled levels is expected, as the effects
of these two events wane.
