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 conjunto USAF/NOAA de actividad Solar y Geofísica

SDF Número 234 Publicado el 2200Z a las 21 Aug 2004

IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z

Solar activity was very low. Occasional brightness fluctuations were noted, but no flare activity occurred. Region 661 (N07W33) contains minor magnetic complexity and white light area coverage of over 450 millionths, but has been stable for the past 48 hours. Region 663 (N11E52) has rotated fully into view as an elongated beta spot group with some minor magnetic mixing. Region 664 (S10E25) exhibited considerable growth this period and also displays some minor mixing. No new regions were numbered today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very low to low. Isolated C-class flares are possible.
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z
The geomagnetic field was quiet to active with isolated minor storm periods. The disturbed periods are due to a slightly elevated solar wind speed (near 500 km/s) and predominantly southward IMF Bz.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected to be quiet to active with isolated minor storm periods.
