SDF Número 233 Publicado el 2200Z a las 21 Aug 2025IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z Solar activity has been at low levels for the past 24 hours.
There are currently 6 numbered sunspot regions on the disk.
IB. Pronóstico de la actividad solar
Solar activity is likely to be low with a
slight chance for an M-class flare on days one and two (22 Aug, 23 Aug)
and expected to be low with a chance for M-class flares on day three (24
Aug).
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z
