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 230 Publicado el 2200Z a las 18 Aug 2005IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z Solar activity was very low. Newly numbered Region 799
(S12W56) was responsible for several B-class flares. LASCO imagery
showed a CME at 18/1654 UTC directed towards the southwest which was
likely associated with a B2 flare which occurred from Region 799 at
18/1605 UTC.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low to low.
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
The geomagnetic field was quiet to active due to the continued
influence of a coronal hole high speed stream. Solar wind speed at
ACE has gradually decreased from approximately 700 km/s to 620 km/s.
The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels today.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to unsettled with a chance of isolated active
periods on 19 August as the coronal hole high speed stream moves out
of geoeffective position. Quiet to unsettled conditions are expected
on 20 - 21 August.
