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 291 Publicado el 2200Z a las 17 Oct 2004

IA. Análisis de regiones solares activas y de actividad desde 16-2100Z hasta 17-2100Z

Solar activity continued at very low levels with occasional B-class flares. Region 682 (S14E10) has shown some decay in white light area coverage, but still maintains minor magnetic complexity. New Region 683 (S09E22) emerged as a C type group early in the period. New Region 684 (S04E65) was also numbered today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very low to low. Isolated minor C-class flares are possible.
IIA. Resumen de la actividad geofísica 16-2100Z a 17-2100Z
The geomagnetic field was quiet. Very stable solar wind conditions persisted through the period. Solar wind speed declined to near 300 km/s and IMF Bz remains near zero. The greater than 2 MeV electron flux at geosynchronous orbit was high, and has been at high levels since 14 October.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected to be quiet to unsettled. Isolated active periods are possible on 19 October due to a weak high speed solar wind stream.
