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 111 Publicado el 2200Z a las 21 Apr 2006IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z Solar activity continued very low. Region 874
(S01W25), the sole spotted region visible, was stable and quiet.
There are signs of new flux emerging in the southeast, where two
small groups are in the formative stage. The limbs were quiet.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low to low.
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z
The geomagnetic field was quiet to active. A period of enhanced solar
wind conditions began around midday, when Alfven waves caused Bz to
reach -10 nT for a brief period. Those fluctuations are still
occurring. The greater than 2 MeV electron flux at GOES was again at
high levels.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be predominantly quiet to unsettled for the next three
days. Solar wind wave activity may persist for the next few hours,
and there is a chance of another short-lived disturbance from
high-speed solar wind on April 23.
