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 118 Publicado el 2200Z a las 28 Apr 2002IA. Análisis de regiones solares activas y de actividad desde 27-2100Z hasta 28-2100Z Solar activity was low. The only C-class flare of the
period was a C1/Sf from Region 9924 (S15W64) at 28/1823Z. No
significant activity or changes were noted in any of the active
regions.
IB. Pronóstico de la actividad solar
Solar activity is expected to continue
at low levels. Regions 9914 (N05W51), 9915 (N12W40) and 9919
(N14E01) have the best potential for isolated C-class flares.
IIA. Resumen de la actividad geofísica 27-2100Z a 28-2100Z
The geomagnetic field was quiet to active. The recurrent high speed
coronal hole stream developed late last period and produced mostly
active conditions during local nighttime hours.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to continue at quiet to active levels. The active periods
will occur predominantly during local nighttime hours.
