Informe actividad solar
Informe de actividad Solar-Geofísica 2025 Dec 28 2200 UTCPreparado por NOAA © SWPC y procesado por SpaceWeatherLive.com
Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 362 Publicado el 2200Z a las 28 Dec 2025IA. Análisis de regiones solares activas y de actividad desde 27-2100Z hasta 28-2100Z 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 low with
a chance for M-class flares and a slight chance for an X-class flare on
days one, two, and three (29 Dec, 30 Dec, 31 Dec).
IIA. Resumen de la actividad geofísica 27-2100Z a 28-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 604 km/s at 28/1526Z. Total IMF reached 7
nT at 28/0913Z. The maximum southward component of Bz reached -5 nT at
28/0901Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 8999 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet levels on days one, two, and three (29 Dec, 30 Dec, 31
Dec). Protons have a slight chance of crossing threshold on days one,
two, and three (29 Dec, 30 Dec, 31 Dec).
