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 231 Publicado el 2200Z a las 19 Aug 2006IA. Análisis de regiones solares activas y de actividad desde 18-2100Z hasta 19-2100Z Solar activity was low. Region 903, a plage region on
the west limb, produced a C3.8 flare at 19/1124Z. Region 904
(S14W54) has shown little activity, producing only B-class flares.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low to low, with a slight chance for an isolated M-class flare from
Region 904.
IIA. Resumen de la actividad geofísica 18-2100Z a 19-2100Z
The geomagnetic field has been at quiet to major storm levels. At
approximately 19/1100Z a small shock was observed at ACE. The total
IMF strength increased to about 20 nT while the Bz component turned
southward and reached -15 nT. The solar wind speed also increased
from about 400 km/s to about 450 km/s. This resulted in two periods
of major storm levels at high latitudes from 1200 - 1800Z. At time
of issue Bz remained southward at approximately -10 nT and solar
wind speed had decreased to about 400 km/s. Today's shock arrival
is likely due to the full halo CME observed on 16 August.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be unsettled to active with a chance for isolated minor
storm periods on 20 August due to an expected coronal hole high
speed stream. Quiet to unsettled conditions are expected on 21 - 22
August.
