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 124 Publicado el 2200Z a las 04 May 2011IA. Análisis de regiones solares activas y de actividad desde 03-2100Z hasta 04-2100Z Solar activity has been very low during the past 24
hours. Region 1204 (N17E13) produced a B9 x-ray event at 04/0144Z.
An eruptive filament was observed in the vicinity of Region 1205
(N14E23) at 04/1656Z. The remaining active regions were quiet and
stable.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low to low during days one through three (05-07 May).
IIA. Resumen de la actividad geofísica 03-2100Z a 04-2100Z
The geomagnetic field has been quiet during the past 24 hours.
Observations from the ACE spacecraft indicate a steady decrease in
solar wind velocity from 600 km/s to around 425 km/s as the recent
coronal hole high speed stream subsided. 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 predominately quiet with isolated unsettled periods
for days one through three (05-07 May).
