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 049 Publicado el 2200Z a las 18 Feb 2005IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z Solar activity was low. Regions 732 (N15W90) and 735
(S09W32) were responsible for several low level C-class flares.
Region 732 produced the largest C-flare; a C2.3 at 17/2344Z.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low.
Region 735 is still capable of producing C-class events.
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
The geomagnetic field was at quiet to minor storm levels. Activity
was due to the effects of a high speed stream from a geoeffective
coronal hole. Solar wind speed at ACE showed an increase to
approximately 600 km/s by 18/1600Z and then decreased slightly to
550 km/s by the end of the period.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be unsettled to active with the possibility of isolated
minor storm levels on 19 February due to the arrival of the CME
observed on LASCO imagery on 17 February. Expect quiet to active
conditions on 20 February and quiet to unsettled conditions on 21
February.
