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 119 Publicado el 2200Z a las 29 Apr 2007IA. Análisis de regiones solares activas y de actividad desde 28-2100Z hasta 29-2100Z Solar activity was very low. Region 953 (S10E23) has
shown a slight decrease in trailing spots bordering the main spot.
Also, the beginnings of a possible separation of penumbral area on
the eastern side of the main spot was noted.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low to low with a chance for an M-flare from Region 953.
IIA. Resumen de la actividad geofísica 28-2100Z a 29-2100Z
The geomagnetic field was at quiet to minor storm conditions.
Increased activity was due to the continued influence of a recurrent
coronal hole high speed stream. The greater than 2 MeV electron flux
at geosynchronous orbit reached high levels again today.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to active with isolated minor storm periods
possible on 30 April. Activity is expected to decrease to quiet to
unsettled levels by 01 and 02 May.
