Informe actividad solar
Informe de actividad Solar-Geofísica 2025 Dec 05 2200 UTCPreparado por NOAA © SWPC y procesado por SpaceWeatherLive.com
Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 339 Publicado el 2200Z a las 05 Dec 2025IA. Análisis de regiones solares activas y de actividad desde 04-2100Z hasta 05-2100Z Solar activity has been at low levels for the past 24 hours.
There are currently 8 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 days one, two, and three
(06 Dec, 07 Dec, 08 Dec).
IIA. Resumen de la actividad geofísica 04-2100Z a 05-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 748 km/s at 05/0710Z. Total IMF reached 8
nT at 05/1708Z. The maximum southward component of Bz reached -5 nT at
05/1917Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 1425 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to active levels on day one (06 Dec) and quiet to minor
storm levels on days two and three (07 Dec, 08 Dec). Protons have a
slight chance of crossing threshold on days one, two, and three (06 Dec,
07 Dec, 08 Dec).
