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 109 Publicado el 2200Z a las 18 Apr 2012IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z Solar activity was low during the past 24 hours. New
Region 1463 (S26W36) produced several C-class and optical flares,
the largest a C8/Sf at 18/1239Z. An associated CME became visible in
STEREO COR2 imagery at 18/1309Z. Further analysis will be conducted
to determine effectiveness as imagery becomes available. Region 1463
also produced a C5 flare at 18/1706Z associated with Type II (est.
speed 621 km/s) and Type IV radio sweeps. No STEREO or LASCO imagery
was available for this event. Further analysis will also be
conducted on this event when imagery is available.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
with a slight chance for an isolated M-class event for the next
three days (19-21 April).
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
The geomagnetic field was quiet to unsettled during the past 24
hours. The increase in activity was due to a slight increase in
solar wind speeds (reaching approximately 475 km/s) and extended
periods of southward Bz.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be mostly quiet on day one (19 April). Quiet to
unsettled conditions are expected on day two (20 April) due to an
anticipated Solar Sector Boundary Crossing. A return to mostly quiet
conditions is expected on day three (21 April).
