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 Mar 20 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 079 Publicado el 2200Z a las 20 Mar 2005IA. Análisis de regiones solares activas y de actividad desde 19-2100Z hasta 20-2100Z Solar activity remained at low levels today. Old
Region 742 (S06 L=160) which rotated off the west solar limb 19
March produced the largest flare of the period, a C4 x-ray event
that occurred at 20/0159 UTC. Region 743 (S08W70) produced multiple
B and C-class flares during the period. The largest was a C2 x-ray
event that occurred at 20/1152 UTC. There was some decay in spot
area today and the beta-gamma magnetic structure weakened but
remains intact. Region 744 (S12E01) is a rapidly forming DSO beta
group and was numbered today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
low levels.
IIA. Resumen de la actividad geofísica 19-2100Z a 20-2100Z
The geomagnetic field was at quiet to unsettled levels.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at predominantly quiet to unsettled levels. Isolated
active periods may be possible at higher latitudes on 22 and 23
March, due to a potentially geoeffective coronal hole.
