SDF Número 111 Publicado el 2200Z a las 21 Apr 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 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 days one, two, and three (22 Apr, 23 Apr,
24 Apr).
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z

field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 745 km/s at 21/1336Z. Total IMF
reached 18 nT at 21/0733Z. The maximum southward component of Bz reached
-14 nT at 21/0803Z. Electrons greater than 2 MeV at geosynchronous
orbit reached a peak level of 452 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at unsettled to major storm levels on day one (22 Apr), quiet to
minor storm levels on day two (23 Apr) and quiet to active levels on day
three (24 Apr).
