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 148 Publicado el 2200Z a las 27 May 2012IA. Análisis de regiones solares activas y de actividad desde 26-2100Z hasta 27-2100Z Solar activity was low. Region 1492 produced a long
duration C-class flare at 27/0552Z. This event was associated with a
CME observed off the southeast limb of the solar disk in LASCO C2/C3
and does not appear to be earth directed. Another more impressive
CME was observed at the end of the period yesterday. No flare was
observed in conjunction due to a source from around the west limb.
However, type II and IV radio sweeps were observed from the event,
in addition to a later observed 10 MeV proton event (NOAA Scale S1).
The CME shock and driver cloud are observable in LASCO C2/C3 as a
backside asymmetric halo and are not expected to be geoeffective.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low to low for the next 3 days (28-30 May).
IIA. Resumen de la actividad geofísica 26-2100Z a 27-2100Z
The geomagnetic field was quiet. The greater than 10 MeV proton event
at geosynchronous orbit that began at 27/0535Z, reached a maximum of
14 pfu at 27/1045Z and ended at 27/1235Z. The greater than 2 MeV
electron flux at geosynchronous orbit reached high levels during the
period.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be mostly quiet for the next 3 days (28-30 May).
