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 255 Publicado el 2200Z a las 12 Sep 2002IA. Análisis de regiones solares activas y de actividad desde 11-2100Z hasta 12-2100Z Solar activity fell to low levels. The largest event
of the period was a C4/Sf flare at 12/0018 UTC from Region 107
(N11E16). Region 105 (S08E16) produced several lesser C-class
flares, including an apparent one in progress at the end of the
period. This region remains the largest on the visible disk. It's
easternmost spots still retain a beta-gamma-delta magnetic
configuration, while the western spot group appears to have lost
some complexity. Region 107 continues in a pattern of slow growth
and frequent flare production. Three new regions were numbered
today, all relatively small and simply structured at present.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
to moderate for the next three days. M-class activity appears
possible from Regions 105 and 107.
IIA. Resumen de la actividad geofísica 11-2100Z a 12-2100Z
The geomagnetic field was mainly unsettled to active. One isolated
quiet period was observed at mid-latitudes. Coronal hole high speed
stream effects continued to be the main source of activity.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to active during the first day of the forecast
period, with a gradual reduction towards quiet to unsettled
conditions thereafter. Greater than 2 MeV electron flux at
geosynchronous orbit may reach high levels during the period.
