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 293 Publicado el 2200Z a las 20 Oct 2010IA. Análisis de regiones solares activas y de actividad desde 19-2100Z hasta 20-2100Z Solar activity was at low levels. Region 1112 (S20W84)
produced the lone event of the period, a C1.5/Sf at 20/1150Z. The
remaining regions were quiet and unchanged.
IB. Pronóstico de la actividad solar
Solar activity is expected to be
predominately very low all three days of the forecast period (21 -
23 October). A chance for an isolated C-class event exists on day
one (21 October) from departing Region 1112, decaying to a slight
chance of C-class activity on days two and three (22 - 23 October).
IIA. Resumen de la actividad geofísica 19-2100Z a 20-2100Z
The geomagnetic field was quiet. Solar wind velocities remained
steady during the period, varying between 420 - 460 km/s while the
Bz component of the interplanetary magnetic field remained
predominately north.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at quiet to unsettled levels, with isolated active
periods on day one (21 October). A small, recurrent coronal hole
high speed stream (CH HSS) is expected to rotate into a geoeffective
position on 21 October. By day two (22 October), field conditions
are expected to be mostly quiet. Late on day three (23 October), a
large, recurrent CH HSS is expected to become geoeffective,
resulting in quiet to active conditions.
