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 141 Publicado el 2200Z a las 20 May 2004IA. Análisis de regiones solares activas y de actividad desde 19-2100Z hasta 20-2100Z Solar activity was low. Newly assigned Region 618
(S10E69) produced all of today's three C-class flares. The other
sunspot regions on the disk were quiet and stable. A filament in the
northeast quadrant erupted at 0136 UTC and was associated with a CME
off the northeast solar limb. The angular width of the CME was
narrow and the transient does not appear to be directed towards
Earth.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low.
Most of the activity is expected to occur in Region 618.
IIA. Resumen de la actividad geofísica 19-2100Z a 20-2100Z
The geomagnetic field was mostly quiet to unsettled. However, there
was a period of minor storm levels from 0900-1200 UTC. Solar wind
data at ACE showed a steady increase in solar wind velocity from
initial values around 380 km/s up to about 500 km/s by forecast
issue time. Elevated solar wind temperature and wave patterns in the
magnetic field data suggest that the enhancement may originate from
a coronal hole.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be mostly unsettled but with a fair chance for some
isolated active periods during the next two days (21-22 May). A
decline to quiet to unsettled is expected around mid-day on the
third day (23 May).
