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 284 Publicado el 2200Z a las 11 Oct 2002IA. Análisis de regiones solares activas y de actividad desde 10-2100Z hasta 11-2100Z Solar activity was low. The most interesting event of
the period was a long-duration C3/Sf event at 11/1719 UTC, with an
associated bright prominence on the west limb near S15. The
presumed source is Region 143 (S16, L=017), which had rotated beyond
the west limb early in the period. Region 139 (N09W46) was a source
of some lesser C-class activity during the period, and remains the
largest sunspot group on the visible disk, with moderate but stable
complexity in its delta magnetic configuration. Region 149 (N15E48)
has exhibited some growth and produced two C-class flares during the
period. Two new regions emerged on the disk and were numbered
today: 155 (S09W53) and 156 (N09E10).
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
to moderate. Regions 139 and 149 are both potential sources of
isolated moderate flare activity.
IIA. Resumen de la actividad geofísica 10-2100Z a 11-2100Z
The geomagnetic field was quiet to unsettled. The greater than 2 MeV
electron flux at geosynchronous orbit reached moderate levels but
remained below event threshold.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be predominantly quiet to unsettled.
