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 145 Publicado el 2200Z a las 25 May 2011IA. Análisis de regiones solares activas y de actividad desde 24-2100Z hasta 25-2100Z Solar activity was very low. Only low level B-class
events were observed during the period. Region 1220 (N12, L=249)
produced a long duration B2 event at 24/2237Z prior to its rotation
around the west limb. Region 1218 (S16W28) also produced B-class
events with frequent point brightenings within the region. This
region remains a spotless plage. A nine degree filament located at
N44E37 disappeared between 25/0801-1256Z. A further analysis of
this event will be performed as image data updates for any
associated CME activity. New Region 1222 (N15W24) was numbered
today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low.
IIA. Resumen de la actividad geofísica 24-2100Z a 25-2100Z
The geomagnetic field was quiet. Solar wind speeds observed by the
ACE spacecraft have averaged around 380 km/s through the period with
occasional minor fluctuations in the IMF Bz between -4/+5 nT.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be mostly quiet on day one (26 May). Quiet to unsettled
conditions, with isolated active levels, are expected for days two
and three (27-28 May) as a recurrent coronal hole high speed stream
becomes geo-effective.
