Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 355 Publicado el 2200Z a las 21 Dec 2025IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z Solar activity has been at moderate levels for the past 24
hours. There are currently 5 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 on days one, two, and three (22 Dec, 23 Dec,
24 Dec).
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z
The geomagnetic
field has been at unsettled to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 723 km/s at 21/2028Z. Total IMF
reached 15 nT at 21/1128Z. The maximum southward component of Bz reached
-11 nT at 21/0544Z. Electrons greater than 2 MeV at geosynchronous
orbit reached a peak level of 2257 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at unsettled to minor storm levels on day one (22 Dec), quiet to
minor storm levels on day two (23 Dec) and unsettled to active levels on
day three (24 Dec).
