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 114 Publicado el 2200Z a las 23 Apr 2012IA. Análisis de regiones solares activas y de actividad desde 22-2100Z hasta 23-2100Z Solar activity has been at low levels for the past 24
hours. There are currently 8 active regions on the disk, with 5
regions having sunspots. The spotted regions on the disk all
remained rather quiet and stable throughout the period. However,
around plage Region 1461 (N10W19), two C-class events were observed
today with associated Earth directed CMEs.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
low levels with a chance for M-class x-ray events for the next three
days (24 - 26 April).
IIA. Resumen de la actividad geofísica 22-2100Z a 23-2100Z
The geomagnetic field has been at quiet to minor storm levels for the
past 24 hours. Observations made by the ACE spacecraft, around
23/0200Z, indicated the arrival of a CME that lifted off the solar
disk on 19 April. Solar wind velocities increased from 350 - 400
km/s with the total IMF reaching around 18 nT. The Boulder
magnetometer measured a 31 nT sudden impulse at 23/0325Z in
conjunction with the CME arrival here at Earth. From then on, active
to minor storm levels were observed due to multiple periods of
sustained negative Bz.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at quiet to active levels with a slight chance for a
minor storm on day 1 (24 April) as effects from the CME wane and a
coronal hole high speed stream (CH HSS) moves in. Quiet to active
levels are expected on day two (25 April) as the effects of the CH
HSS continue. An increase to quiet to minor storm levels are
expected on day three (26 April) as the two CMEs, observed earlier
in the period, are expected to become geoeffective.
