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 113 Publicado el 2200Z a las 22 Apr 2012IA. Análisis de regiones solares activas y de actividad desde 21-2100Z hasta 22-2100Z Solar activity was low. Occasional low-level C-class
flares occurred. Region 1459 (S15W25 - Dki/beta) produced a single
C-class flare and showed signs of gradual decay in its intermediate
portion. Region 1465 (S18E14 - Dai/beta) produced two C-class flares
and showed spot and penumbral development as well as some polarity
mixing in its intermediate portion. New Region 1466 (N12E29 -
Cso/beta) emerged early in the period and gradually grew. No
Earth-directed CMEs were observed during the period.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
through the period (23 - 25 April) with a chance for an isolated
M-class flare.
IIA. Resumen de la actividad geofísica 21-2100Z a 22-2100Z
Geomagnetic field activity was at quiet to unsettled levels with a
brief interval of active levels at high latitudes.
IIB. Pronóstico de la actividad geofísica
Geomagnetic field activity is
expected to be at quiet to unsettled levels during days 1 - 2 (23 -
24 April) with a chance for active levels due mainly to a recurrent
coronal hole high-speed stream. Weak CME-passage effects are also
possible on day 1 from the partial-halo CME observed on 19 April.
Field activity is expected to decrease to mostly quiet levels on day
3 (25 April).
