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 155 Publicado el 2200Z a las 04 Jun 2011IA. Análisis de regiones solares activas y de actividad desde 03-2100Z hasta 04-2100Z Solar activity was low. Region 1226 (S21W25) produced
a C1 at 03/2242Z. This region remains a D-type group with a beta
magnetic classification. All other numbered regions remained stable.
No new regions were numbered today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
with a slight chance for a M-class event.
IIA. Resumen de la actividad geofísica 03-2100Z a 04-2100Z
The geomagnetic field was quiet to active. The ACE spacecraft
detected an interplanetary shock passage at 04/1958Z. Solar winds
jumped from around 325 km/s to 455 km/s, density increased, and the
IMF Bt went from 5nT to 20 nT. A geomagnetic sudden impulse was
observed at 04/2045Z (54 nT) on the Boulder USGS magnetometer. This
signature is consistent with the arrival of a CME. The greater than
2 MeV electron flux at geosynchronous orbit was at high levels
throughout the period.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be mostly active with isolated minor storm conditions,
and isolated major storming at high-latitudes, for day one (05
June). The source for the activity is a combination of continued
CME effects, and the arrival of a geoeffective coronal hole
high-speed stream. For day two (06 June) the geomagnetic field is
expected to be quiet to unsettled with isolated active conditions.
By day three (07 June) mostly quiet to unsettled levels are expected
as the activity subsides.
