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 078 Publicado el 2200Z a las 19 Mar 2005IA. Análisis de regiones solares activas y de actividad desde 18-2100Z hasta 19-2100Z Solar activity was at low levels today. Region 743
(S08W57) produced two C-class flares during the period. The largest
was an impulsive C2/Sf flare that occurred at 19/0707 UTC. A Type
II radio sweep accompanied this flare and had an estimated shock
velocity of 413 km/s. SOHO/LASCO imagery did not depict any
significant CME activity near the time of the event. Region 743
continues to exhibit a beta-gamma magnetic structure. Region 742
(S06 L=160) rotated off the solar west limb today. No new regions
were numbered today
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
very low to low levels.
IIA. Resumen de la actividad geofísica 18-2100Z a 19-2100Z
The geomagnetic field ranged from quiet to minor storm levels. An
isolated period of minor storming occurred between 19/0000 and 0300
UTC. This was most likely due to a sustained southward Bz and a
slight increase in the solar wind speeds to approximately 460 km/s.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at predominantly quiet to unsettled levels.
