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 359 Publicado el 2200Z a las 25 Dec 2014IA. Análisis de regiones solares activas y de actividad desde 24-2100Z hasta 25-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C4 event observed at
25/1211Z from Region 2248 (S20E47). There are currently 7 numbered
sunspot regions on the disk.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low with
a chance for M-class flares on days one, two, and three (26 Dec, 27 Dec,
28 Dec).
IIA. Resumen de la actividad geofísica 24-2100Z a 25-2100Z
The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
557 km/s at 24/2139Z. Total IMF reached 10 nT at 25/1901Z. The maximum
southward component of Bz reached -9 nT at 25/1838Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 431 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet levels on day one (26 Dec) and quiet to unsettled levels
on days two and three (27 Dec, 28 Dec).
