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 050 Publicado el 2200Z a las 19 Feb 2003IA. Análisis de regiones solares activas y de actividad desde 18-2100Z hasta 19-2100Z Solar activity was at low levels. Region 290 (N18E30)
produced a C1.8/Sf at 19/1437 UTC. This region has shown growth in
area coverage, and has formed a beta-gamma magnetic configuration in
the leader spots. Region 289 (N09W66) has shown rapid growth in the
last 24 hours, but has maintained a beta magnetic configuration.
Activity from Region 289 consisted of bright surging along the
southwest portion of the region.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
low levels with a slight chance of isolated M-class activity from
Regions 289 and 290.
IIA. Resumen de la actividad geofísica 18-2100Z a 19-2100Z
The geomagnetic field was at quiet to unsettled levels. The
transient effects that began yesterday, and produced a structured
solar wind, appear to be ending. At 19/1400 UTC, the steady decline
in solar wind velocity reached a minimum near 500 km/s. Solar wind
velocity has since increased to 560 km/s. Bz show signs of
returning to the fluctuating signature of a high speed stream.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at quiet to isolated active conditions. An
equatorial coronal hole has entered a geo-effective position, and is
expected to produce high speed stream effects.
