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
:::::::::: CORRECTED COPY :::::::::: SDF Número 097 Publicado el 2200Z a las 07 Apr 2011IA. Análisis de regiones solares activas y de actividad desde 06-2100Z hasta 07-2100Z Solar activity was at low levels. Four C-class flares
were observed during the period from a region on the NE limb. New
Region 1187 (S19E62) was numbered today as an alpha group. A CME was
observed from the SE limb on SOHO/LASCO C3 imagery at 07/0754Z, with
a speed of approximately 548 km/s. The origin of the CME appears to
be an active filament channel in the SE quadrant. This CME is not
expected to be geoeffective. A second CME was observed from the SW
limb on SOHO/LASCO C3 imagery at 07/1042Z, with an approximate
speed of 824 km/s. The origin appears to be a flare from old Region
1176, which rotated off the west limb on 04 April. This CME is also
not expected to be geoeffective.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
very low to low levels.
IIA. Resumen de la actividad geofísica 06-2100Z a 07-2100Z
The geomagnetic field was at predominantly quiet levels. A single
unsettled activity period was observed between 07/0000Z - 07/0300Z.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at quiet levels on days one and two (08-09 April).
Activity is expected to increase on day three (10 April) due to a
coronal hole high-speed stream.
