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 232 Publicado el 2200Z a las 19 Aug 2012IA. Análisis de regiones solares activas y de actividad desde 18-2100Z hasta 19-2100Z Solar activity was moderate. Region 1548 (N19E62)
produced two M-class flares, an M1/Sf at 18/2254Z and an M1/Sn flare
at 18/2322Z. Activity then decreased to low levels for the
remainder of the period. Region 1548 decreased in area and ended
the period as a Cso type group with beta magnetic characteristics.
New Region 1549 (S16W30) was numbered today and also a simple
Cso-beta type group.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
with a chance for an M-class event for the next three days (20-22
August).
IIA. Resumen de la actividad geofísica 18-2100Z a 19-2100Z
The geomagnetic field ranged from quiet to unsettled levels. A
coronal hole high speed stream became geoeffective during the past
24 hours. At approximately 18/08Z, solar wind speed at the ACE
spacecraft began increasing from about 400 km/s to 580 km/s.
Shortly after, the Bz component of the interplanetary magnetic field
(IMF) became negative, eventually reaching -12nT. Bz returned to
positive values around 14Z. Earth is currently in the positive
sector of the IMF.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at mostly unsettled levels with a chance for active
conditions on day 1 (20 August), decreasing to a slight chance on
days 2-3 (21-22 August). The disturbed conditions are expected in
response to the continued presence of the coronal hole high speed
stream.
