Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 292 Publicado el 2200Z a las 19 Oct 2025IA. Análisis de regiones solares activas y de actividad desde 18-2100Z hasta 19-2100Z Solar activity has been at moderate 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 expected to be low with
a chance for M-class flares on day one (20 Oct) and expected to be low
with a slight chance for an M-class flare on days two and three (21 Oct,
22 Oct).
IIA. Resumen de la actividad geofísica 18-2100Z a 19-2100Z

field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 621 km/s at 19/1936Z. Total IMF
reached 13 nT at 18/2324Z. The maximum southward component of Bz reached
-9 nT at 19/1654Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 443 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to active levels on day one (20 Oct) and quiet to
unsettled levels on days two and three (21 Oct, 22 Oct).
