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 138 Publicado el 2200Z a las 18 May 2011IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z Solar activity has been low for the last 24 hours. New
Region 1218 (S16E66) was numbered today and produced a C1 event at
18/1259Z. Region 1208 (N09W90) produced a long duration C2 event at
18/1830Z just as it was rotating around the west limb. All other
regions on the disk remained relatively quiet and stable.
IB. Pronóstico de la actividad solar
Solar activity is expected to remain
very low with a chance for C-class activity for the next three days
(19-21 May) as new Region 1218 continues to develop.
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
The geomagnetic field has been mostly quiet for the last 24 hours.
Solar wind at ACE showed a decrease from approximately 550 km/s to
450 km/s during the period as effects from the coronal hole high
speed stream subside.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet for the next three days (19-21 May) as the
solar wind returns to background levels.
