Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 51 Publicado el 2200Z a las 20 Feb 2025IA. Análisis de regiones solares activas y de actividad desde 19-2100Z hasta 20-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C8 event observed at
19/2345Z from Region 3991 (S14W38). 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 and a slight chance for an X-class flare on
days one, two, and three (21 Feb, 22 Feb, 23 Feb).
IIA. Resumen de la actividad geofísica 19-2100Z a 20-2100Z
The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 508 km/s at 20/0439Z. Total IMF reached 7
nT at 20/0206Z. The maximum southward component of Bz reached -7 nT at
19/2349Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 307 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet levels on days one, two, and three (21 Feb, 22 Feb, 23
Feb).
