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 May 20 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 140 Publicado el 2200Z a las 20 May 2005IA. Análisis de regiones solares activas y de actividad desde 19-2100Z hasta 20-2100Z Solar activity was at very low levels. Region 759
(N12W88) is transiting the solar west limb and quiescent throughout
the period. Region 765 (N09E51) was responsible for several low
level B-class flares today. Magnetically, this region remains
simply structured. No new regions were numbered today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
very low levels with a slight chance for an isolated C-class flare.
IIA. Resumen de la actividad geofísica 19-2100Z a 20-2100Z
The geomagnetic field ranged from quiet to major storming levels
today. The most likely source for the major storming conditions was
the full halo CME seen early on 17 May. The greater than 2 MeV
electron flux at geosynchronous orbit reached high levels.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field should be
at quiet to unsettled levels throughout the period.
