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 300 Publicado el 2200Z a las 27 Oct 2002IA. Análisis de regiones solares activas y de actividad desde 26-2100Z hasta 27-2100Z Solar activity was low during the past 24 hours.
Today's activity consisted of occasional low-level C-class flares,
all from Region 162 (N26W43). Region 162 showed emergence of new
flux in the northwest portion of the trailing spots, leading to the
formation of a new delta configuration. A large, southern polar
crown filament lifted of the disk around 0900 UTC on the 27th and
was observed as a small CME in the LASCO C3 field of view.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
to moderate during the next three days. There is a fair chance for
an isolated M-class event from Region 162. The newly formed delta
configuration also poses a slight threat for major flare activity.
IIA. Resumen de la actividad geofísica 26-2100Z a 27-2100Z
The geomagnetic field was unsettled to active during the past 24
hours. The magnetosphere continues to be under the influence of a
high speed solar wind stream with persistently negative orientation
of the interplanetary magnetic field component Bz. The greater the 2
MeV electron fluxes reached high levels during the past 24 hours.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be unsettled to active during the next 12-24 hours due
to persistent effects of the high speed solar wind stream.
Predominantly unsettled levels are expected for the second and third
days.
