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 050 Publicado el 2200Z a las 19 Feb 2005IA. Análisis de regiones solares activas y de actividad desde 18-2100Z hasta 19-2100Z Solar activity increased to moderate levels. An M3
x-ray flare occurred at 19/1101Z from just beyond the solar west
limb. The source of this flare appears to be from the vicinity of
Region 732 (N08 L=188) which rotated out of view early yesterday.
Region 735 (S09W45) underwent a slight decay in overall sunspot
coverage today while the southern most penumbral mass had a
noticeable increase in area. Magnetic analysis indicates Region 735
has the characteristics of a beta-gamma class group. The remaining
active regions were quiescent today. No new regions were numbered
today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
low levels. Region 735 has the potential of producing isolated
C-class flares.
IIA. Resumen de la actividad geofísica 18-2100Z a 19-2100Z
The geomagnetic field ranged from quiet to active levels today. A
recurrent high speed coronal hole stream is the most likely source
for the active conditions. The solar wind speeds have ranged from
550 km/s down to 450 km/s throughout the period. The greater than 2
MeV electron flux at geosynchronous orbit briefly reached high
levels today.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at predominantly quiet to unsettled levels throughout
the period.
