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 095 Publicado el 2200Z a las 04 Apr 2008IA. Análisis de regiones solares activas y de actividad desde 03-2100Z hasta 04-2100Z Solar activity was very low. Spotless plage Region 989
(S11W54) produced isolated B-class subflares. No new regions were
numbered.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low to low. There is a fair chance for an isolated C-class flare
from Region 989.
IIA. Resumen de la actividad geofísica 03-2100Z a 04-2100Z
Geomagnetic field activity was at quiet to active levels. Field
activity increased to active levels during 04/1800 - 2100Z due to
increased solar wind velocities and IMF magnitude combined with
periods of southward IMF Bz. ACE signatures indicated Earth entered
the co-rotating interaction region between slow and fast solar wind
flows. Velocities increased to 507 km/sec near the close of the
summary period. The greater than 2 MeV electron flux at
geosynchronous orbit was high during most of the period.
IIB. Pronóstico de la actividad geofísica
Geomagnetic field activity is
expected to be at active levels during days 1 - 2 (05 - 06 April)
with minor to major storm periods at high latitudes due to coronal
hole effects. Field activity is expected to decrease to unsettled
levels on day 3 (07 April) with active to minor storm periods at
high latitudes as coronal hole effects decrease.
