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 139 Publicado el 2200Z a las 19 May 2011IA. Análisis de regiones solares activas y de actividad desde 18-2100Z hasta 19-2100Z Solar activity was low during the past 24 hours. A long
duration B3 event occurred in association with a filament eruption
at 19/0436Z centered near N20W25. An associated CME became visible
in LASCO C2 imagery at 19/0436Z but is not expected to cause
significant activity at Earth. Region 1217 (S23W50) decayed to plage
during the period. All other regions on the disk remained relatively
quiet and stable.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low with a chance for isolated C-class events for the next three
days (20-22 May).
IIA. Resumen de la actividad geofísica 18-2100Z a 19-2100Z
The geomagnetic field was quiet during the past 24 hours.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to unsettled for days one and two (20-21 May)
due to weak effects from the CME observed at 18/1842Z off the west
limb. A return to quiet conditions is expected on day three (22
May).
