Informe actividad solar
Informe de actividad Solar-Geofísica 2025 Dec 11 2200 UTCPreparado por NOAA © SWPC y procesado por SpaceWeatherLive.com
Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 345 Publicado el 2200Z a las 11 Dec 2025IA. Análisis de regiones solares activas y de actividad desde 10-2100Z hasta 11-2100Z Solar activity has been at moderate levels for the past 24
hours. There are currently 7 numbered sunspot regions on the disk.
IB. Pronóstico de la actividad solar
Solar activity is likely to be moderate
with a slight chance for an X-class flare on day one (12 Dec) and likely
to be moderate on days two and three (13 Dec, 14 Dec).
IIA. Resumen de la actividad geofísica 10-2100Z a 11-2100Z
The geomagnetic
field has been at quiet to major storm levels for the past 24 hours.
Solar wind speed reached a peak of 500 km/s at 10/2232Z. Total IMF
reached 21 nT at 11/0716Z. The maximum southward component of Bz reached
-16 nT at 11/0059Z. Electrons greater than 2 MeV at geosynchronous
orbit reached a peak level of 539 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at unsettled to active levels on day one (12 Dec) and quiet to
active levels on days two and three (13 Dec, 14 Dec). Protons greater
than 10 Mev have a slight chance of crossing threshold on day one (12
Dec).
