Informe actividad solar
Informe de actividad Solar-Geofísica 2025 Dec 01 2230 UTCPreparado por NOAA © SWPC y procesado por SpaceWeatherLive.com
Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 335 Publicado el 2200Z a las 01 Dec 2025IA. Análisis de regiones solares activas y de actividad desde 30-2100Z hasta 01-2100Z Solar activity has been at high levels for the past 24 hours.
There are currently 9 numbered sunspot regions on the disk.
IB. Pronóstico de la actividad solar
Solar activity is expected to be moderate
with a chance for X-class flares on day one (02 Dec) and likely to be
moderate with a chance for X-class flares on days two and three (03 Dec,
04 Dec).
IIA. Resumen de la actividad geofísica 30-2100Z a 01-2100Z
The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 626 km/s at 30/2317Z. Total IMF reached 6
nT at 01/1639Z. The maximum southward component of Bz reached -5 nT at
30/2311Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 8521 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet levels on day one (02 Dec), quiet to major storm levels
on day two (03 Dec) and active to major storm levels on day three (04
Dec). Protons have a chance of crossing threshold on day one (02 Dec),
have a slight chance of crossing threshold on day two (03 Dec) and have
a slight chance of crossing threshold on day three (04 Dec).
