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 238 Publicado el 2200Z a las 26 Aug 2011IA. Análisis de regiones solares activas y de actividad desde 25-2100Z hasta 26-2100Z Solar activity was at low levels. Region 1271 (N17W69)
produced two C-class events during the period, the largest a C2
x-ray event at 26/1313Z. The region continued to exhibit decay in
spot count, area and magnetic complexity. Other activity consisted
of a B9 x-ray event from Region 1279 (N13E61), observed at 26/1333Z.
New Region 1280 (N17E24) emerged on the disk as a simple bi-polar
spot group. The remainder of the regions were quiet and stable.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
for the next three days (27 - 29 August). A slight chance for
M-class activity exists on days one and two from Region 1271 before
the region rotates around the west limb on 28 August.
IIA. Resumen de la actividad geofísica 25-2100Z a 26-2100Z
The geomagnetic field was quiet. Observations from the ACE spacecraft
indicated steady conditions with wind speeds averaging about 400
km/s.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to remain at quiet levels for day one (27 August). By day
two (28 August), activity levels are expected to increase to quiet
to unsettled, with isolated active periods, due to a geoeffective,
recurrent coronal hole high speed stream. The conditions are
expected to persist through day three (29 August).
