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 108 Publicado el 2200Z a las 18 Apr 2003IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z Solar activity has been at moderate levels. There were
several minor C-class events during the last 24 hours with a single
M1.1 from Region 337 (S12E74) at 1958 UTC. A 13 degree disappearing
solar filament was observed early in the period near Region 335
(S25E21). There was a small coronal mass ejection associated with
that filament, but it was not earth-directed.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
low to moderate levels for the entire period. Region 337 (S12E74)
is just coming on to the visible disk, and appears in solar x-ray
imagery to be a potentially active region.
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
The geomagnetic field was at unsettled to active levels with an
isolated quiet period from 0300 UTC to 0600 UTC. The coronal hole
induced high speed solar wind stream continues. The greater than 2
MeV electron fluxes at geo-synchronous orbit reached high levels
today.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at mostly unsettled levels as the current disturbance
continues to transition out of geoeffective range. Continued
unsettled levels are expected through day two, with a further
decrease to mostly quiet levels on day three.
