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 128 Publicado el 2200Z a las 07 May 2004IA. Análisis de regiones solares activas y de actividad desde 06-2100Z hasta 07-2100Z Solar activity was low. Region 605 (S12W45) produced a
C1/Sf flare at 07/1403Z. A rather faint CME was visible on LASCO
imagery following this flare. Region 605 continues to gradually
decay and now exists as a simple alpha spot group. New Region 606
(S09E81) rotated into view on the east limb during this period. Limb
proximity makes it difficult to accurately assess true size and
complexity; however, a CME was observed to erupt from this location
at 07/1050Z. An associated Type II radio sweep (739 km/s) also
occurred. No other significant activity was noted.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low.
New Region 606 possesses the best potential for C-class activity.
IIA. Resumen de la actividad geofísica 06-2100Z a 07-2100Z
The geomagnetic field was quiet to active. The high speed coronal
hole stream that became geoeffective on 05 May continues to buffet
the geomagnetic field. Frequent southward IMF Bz oscillations over
the last 24 hours are responsible for the most disturbed periods.
The high speed stream does appear to be subsiding: solar wind speed
decreased to below 500 km/s late in the period. The greater than 2
MeV electron flux at geosynchronous orbit reached high levels today.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to active. Isolated active periods are possible
early on 08 May as the coronal hole high speed stream subsides. Weak
transient material from today's C1 flare and CME may produce
occasional unsettled to active periods on 10 May.
