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 199 Publicado el 2200Z a las 18 Jul 2003IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z Solar activity was at low levels. Region 410 (S11W01)
produced two consecutive C5 flares at 17/2356Z and 18/0005Z. Region
410 continues to increase in area coverage and magnetic complexity.
Region 412 (N17W06) exhibited growth in area and magnetic
complexity, developing a beta-gamma magnetic configuration due to
mixing polarities in the trailing spots. Region 409 (N15E05)
continued its gradual decay and simplified to a beta magnetic
configuration. New Region 414 (S02E58) was numbered today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
to moderate. Regions 410, and 412 have the potential for M-class
activity over the next three days. Region 409 has the potential for
M-class activity on day one.
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
The geomagnetic field has been quiet to active. Active conditions
were observed early in the period. Solar wind speed decreased from
600 km/s to 500 km/s around 18/0700Z and remained at 500 km/s for
the remainder of the day. This decrease marks the end of the
coronal hole high speed stream.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at quiet to unsettled levels. Isolated active
conditions are possible during night time hours.
