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 110 Publicado el 2200Z a las 19 Apr 2012IA. Análisis de regiones solares activas y de actividad desde 18-2100Z hasta 19-2100Z Solar activity was low. The largest event of the period
was a C7 x-ray flare at 19/1126Z associated with Types II and IV
radio sweeps and a non-Earth-directed CME. This event may have
originated in old Region 1455 (N05, L=206), now about two days
beyond the west limb. Regions 1460 (N16W01) and 1463 (S26W49) each
produced a low-level C-class flare. Region 1460 showed spot growth
in its intermediate portion. Region 1462 (S24W31) produced a C1
flare at 19/1515Z associated with a CME that may have had an
Earthward component. Further analysis is required to determine if
the CME is likely to be geoeffective. New Region 1464 (N23E01,
Bxo-Beta) was numbered.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
during days 1 - 3 (20 - 22 April) with a chance for an isolated
M-class flare.
IIA. Resumen de la actividad geofísica 18-2100Z a 19-2100Z
The geomagnetic field was quiet.
IIB. Pronóstico de la actividad geofísica
Geomagnetic field activity is
expected to be at quiet to unsettled levels on day 1 (20 April) with
a chance for brief active levels due to a recurrent solar sector
boundary crossing. Quiet levels are expected during days 2- 3 (21 -
22 April).
