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 117 Publicado el 2200Z a las 26 Apr 2012IA. Análisis de regiones solares activas y de actividad desde 25-2100Z hasta 26-2100Z Solar activity was at low levels. Region 1460 (N15W93)
and Region 1465 (S18W39) both produced C1 x-ray events at 25/2242Z
and 26/1723Z respectively. Both had associated CMEs but neither are
expected to be geoeffective. Three consecutive CMEs appeared on
LASCO/C2 imagery at 26/0924Z, 26/1148Z, and 26/1638Z. All three
were around the west limb and are not expected to be geoeffective.
IB. Pronóstico de la actividad solar
Solar activity is expected to remain
low with a slight chance for M-class activity for the next three
days (27 - 29 April).
IIA. Resumen de la actividad geofísica 25-2100Z a 26-2100Z
The geomagnetic field started the period at minor storm levels, but
fell to quiet levels and remained mostly quiet for the remainder of
the period. This activity was attributed to Coronal Hole High Speed
Stream (CH HSS) effects. Solar wind speeds have steadily decreased
from approximately 730 km/s to approximately 560 km/s. The Bz
component of the interplanetary magnetic field has remained fairly
neutral with minor fluctuations between +3 and -5 nT. Overall, the
total field fluctuated between +2 and +8 nT. The greater than 2 MeV
electron flux at geosynchronous orbit was at high levels throughout
the period.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at quiet to unsettled levels with isolated active
periods for day one (27 April) as CH HSS effects begin to wane.
Days two and three (28 -29 April) are expected to be mostly quiet.
