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 25 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 084 Publicado el 2200Z a las 25 Mar 2005IA. Análisis de regiones solares activas y de actividad desde 24-2100Z hasta 25-2100Z Solar activity was low. Region 745 (N12E03) produced a
C1/Sf flare at 24/2344Z. This region is in a slow growth phase with
minor magnetic mixing. No other significant activity was observed on
the solar disk or limb.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
to very low. An isolated C-class flare is possible from Region 745.
IIA. Resumen de la actividad geofísica 24-2100Z a 25-2100Z
The geomagnetic field was quiet to active with isolated minor storm
periods at high latitudes. The most disturbed geomagnetic conditions
followed short periods of southward IMF Bz to near -10 nT. A high
speed coronal hole stream rotated into a geoeffective position over
the past 24 hours. Solar wind speed began the period at just over
400 km/s, but increased to near 700 km/s by the end of the period.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to continue at quiet to active levels. Minor storm periods
are possible at high latitudes on 26 March. Mostly quiet to
unsettled levels with just isolated active periods are expected on
27 and 28 March as the high speed solar wind stream subsides.
