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 18 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 108 Publicado el 2200Z a las 18 Apr 2005IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z Solar activity was low. Region 755 (S11E67) produced a
C4.6 flare at 17/2107 UTC. An associated CME was first observed on
LASCO C2 imagery at 17/2126 UTC off the east limb. The CME is not
expected to be geoeffective. No new regions were numbered today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low to low.
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
The geomagnetic field was quiet to unsettled with an isolated active
period at mid latitudes. 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 quiet to unsettled with possible isolated active
conditions due to the effects of a coronal hole high speed stream
moving into geoeffective position.
