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 de actividad Solar-Geofísica 2005 Apr 17 2210 UTC# Prepared jointly by the U.S. Dept. of Commerce, NOAA, #Space Environment Center and the U.S. Air Force. #
Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 107 Publicado el 2200Z a las 17 Apr 2005IA. Análisis de regiones solares activas y de actividad desde 16-2100Z hasta 17-2100Z Solar activity has been low. Newly numbered Region 755
(S11E76) generated three C-class events on 17 Apr, two near 1300Z
and one at 2054Z. All other regions remain steady.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low.
Region 755 has the continued potential to produce C-class activity.
IIA. Resumen de la actividad geofísica 16-2100Z a 17-2100Z
The geomagnetic field has been at quiet to unsettled levels. The
greater than 2 MeV electron flux at geosynchronous orbit reached
high levels today.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at quiet to unsettled levels. There's a chance for
isolated periods of active levels as a high-speed stream from a
small, but well defined coronal hole rotates into potentially
geoeffective range from 19 - 20 Apr.
