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 104 Publicado el 2200Z a las 13 Apr 2012IA. Análisis de regiones solares activas y de actividad desde 12-2100Z hasta 13-2100Z Solar activity was very low. Region 1455 (N07W19)
produced occasional B-class x-ray flares. It showed gradual spot and
penumbral growth during the period as well as a mix of polarities in
its intermediate and trailer portions, which indicated a beta-gamma
magnetic structure. New Region 1457 (N22E41) was numbered.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low during days 1 - 3 (14 - 16 April) with a chance for isolated
C-class flares from Region 1455.
IIA. Resumen de la actividad geofísica 12-2100Z a 13-2100Z
Geomagnetic field activity ranged from quiet to minor storm levels
with a brief period of major storm at high latitudes. The increased
field activity was associated with a persistent coronal hole
high-speed stream (CH HSS). Solar winds speeds gradually increased
during the first half of the period (maximum speed 693 km/s at
13/0846Z), then gradually decreased during the second half of the
period (minimum speed 544 km/s at 13/1941Z).
IIB. Pronóstico de la actividad geofísica
Geomagnetic field activity is
expected to be at quiet to unsettled levels during days 1 - 2 (14 -
15 April) with a chance for active levels due to persistent CH HSS
effects. Activity is expected to decrease to mostly quiet levels on
day 3 (16 April) as the CH HSS subsides.
