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 114 Publicado el 2200Z a las 23 Apr 2008IA. Análisis de regiones solares activas y de actividad desde 22-2100Z hasta 23-2100Z Solar activity was very low. No flares occurred during
the past 24 hours. Region 992 (N13W17) has been quiet and stable and
is a small, simple C-type sunspot group.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low.
IIA. Resumen de la actividad geofísica 22-2100Z a 23-2100Z
The geomagnetic field was initially unsettled but after 0300Z
increased to predominantly active levels. In addition there were two
minor storm periods; the first from 0600-0900Z and the second from
1500-1800Z. ACE real-time solar wind data show a slow increase in
solar wind speeds at the beginning of the period followed by a
marked increase in speed and temperature around 0400Z. The magnetic
field observations at ACE also indicate a gradual increase as well
as an extended period of mostly southward Bz from 0200Z to about
1700Z. The signatures are consistent with a co-rotating interaction
region followed by a high speed solar wind stream. Solar wind speed
remains elevated with values around 640 km/s at forecast issue time.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be unsettled to active with a chance for isolated minor
storm periods for the first day (24 April) as the high speed stream
persists. Activity is expected to decline to predominantly unsettled
for the second day (25 April) and to predominantly quiet for the
third data (26 April).
