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 05 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 095 Publicado el 2200Z a las 05 Apr 2005IA. Análisis de regiones solares activas y de actividad desde 04-2100Z hasta 05-2100Z Solar activity was low. A C1.1/SF flare occurred from
Region 747 (S05W47) at 05/2007 UTC. New Region 750 (S08E84) was
numbered today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low to low.
IIA. Resumen de la actividad geofísica 04-2100Z a 05-2100Z
The geomagnetic field was at unsettled to severe storm levels. Major
storm periods at middle latitudes with severe storm periods at
higher latitudes were observed between 05/0000 UTC and 05/0600 UTC.
At approximately 0200 UTC on 05 April, solar wind speed at ACE
increased from 560 km/s to 650 km/s while temperature, density, and
the IMF decreased. In addition, Bz remained southward for several
hours following this sudden change. 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 unsettled to active with isolated minor storm periods
possible on 06 April. On 07 and 08 April, quiet to unsettled
conditions are expected as the coronal hole high speed stream moves
out of geoeffective position.
