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 28 2200 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 118 Publicado el 2200Z a las 28 Apr 2005IA. Análisis de regiones solares activas y de actividad desde 27-2100Z hasta 28-2100Z Solar activity increased to low levels. Region 756
(S06E29) produced a C3 x-ray event that occurred at 28/0236Z. White
light analysis indicates that the sunspot area coverage is now at
1030 millionths. Magnetic analysis shows a solid delta structure
seen as the appendage in the southern portion of the large spot. A
second weaker delta structure is seen near the central trailing
portion of the large spot. A newly formed DAO beta spot group was
numbered as Region 757 (S05E03) today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
low levels. Region 756 has the potential of producing an isolated
M-class flare.
IIA. Resumen de la actividad geofísica 27-2100Z a 28-2100Z
The geomagnetic field was at quiet levels today.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at quiet to unsettled levels for 29 and 30 April.
Active to minor storm conditions are possible on 01 May due to the
onset of a recurrent high speed coronal stream.
