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 262 Publicado el 2200Z a las 18 Sep 2012IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z Solar activity has been at low levels for the past 24
hours. New Region 1575 (N07E75) was responsible for the only C-class
event today, which was a C1 x-ray event at 1009Z. This region was
also responsible for the two C-class events observed yesterday. When
Region 1575 rotated onto the visible disk, it had a beta magnetic
classification. No Earth directed CMEs were detected in the past 24
hours.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
low levels with a slight chance for M-class events for the next
three days (19-21 September).
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
The geomagnetic field has been at quiet to unsettled levels for the
past 24 hours. Solar wind speeds, as measured by the ACE spacecraft,
indicated nominal background speeds with sustained periods of the
negative Bz component of the IMF.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to remain at quiet to unsettled levels for the next two
days (19-20 September). A slight increase to quiet to unsettled
levels with chance for active periods is expected on day three (21
September) as a coronal hole high speed stream moves into a
geoeffective position.
