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 115 Publicado el 2200Z a las 24 Apr 2004IA. Análisis de regiones solares activas y de actividad desde 23-2100Z hasta 24-2100Z Solar activity was moderate. Region 597, which has
rotated beyond west limb at latitude S08, produced an M1 flare at
23/2112 UTC. The region produced numerous additional C-class flares
through around 1400 UTC, but is now behind the limb. Newly numbered
Region 599 (N14E51) emerged on the disk and grew steadily. The
region had an area of 120 millionths with mature penumbra on the
leader and trailer by the time of forecast issue (24/2200 UTC). The
group has been producing frequent upper level B-class and lower
level C-class flares. Region 596 (S09W21) continues to be the
largest group on the disk but was stable and appears to be decaying.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low.
Region 599 is expected to be the most productive group, although
Region 596 might contribute some activity. There is a slight chance
for an isolated M-class event sometime during the next three days.
IIA. Resumen de la actividad geofísica 23-2100Z a 24-2100Z
The geomagnetic field was mostly quiet to unsettled. There was an
isolated active period at high latitudes between 0900-1200 UTC.
Solar wind speed remains slightly elevated with values running
between 420 to 480 km/s.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be mostly unsettled with a chance for isolated active
periods at high latitudes for the next 24 hours (25 April).
Conditions should decline to mostly unsettled levels at all
latitudes for the second and third days.
