Informe actividad solar
Informe de actividad Solar-Geofísica 2025 Dec 03 2250 UTCPreparado por NOAA © SWPC y procesado por SpaceWeatherLive.com
Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 336 Publicado el 2235Z a las 03 Dec 2025IA. Análisis de regiones solares activas y de actividad desde 02-2100Z hasta 03-2100Z Solar activity has been at low levels for the past 24 hours.
There are currently 10 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 days one, two, and three (04 Dec, 05
Dec, 06 Dec).
IIA. Resumen de la actividad geofísica 02-2100Z a 03-2100Z
The geomagnetic
field has reached strong storm levels in the past 24 hours. Solar
wind speed reached a peak of 530 km/s at 03/0529Z. Total IMF reached 17
nT at 03/2055Z. The maximum southward component of Bz reached -13 nT at
03/2034Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 8540 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at major to strong storm levels on day one (04 Dec), active to
major storm levels on day two (05 Dec) and active levels on day three
(06 Dec). Protons have a slight chance of crossing threshold on days
one, two, and three (04 Dec, 05 Dec, 06 Dec).
