SDF Número 140 Publicado el 2200Z a las 20 May 2021IA. Análisis de regiones solares activas y de actividad desde 19-2100Z hasta 20-2100Z Solar activity has been at very low levels for the past 24
hours. There are currently 1 numbered sunspot regions on the disk.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very low
with a slight chance for a C-class flare on day one (21 May) and
expected to be very low on days two and three (22 May, 23 May).
IIA. Resumen de la actividad geofísica 19-2100Z a 20-2100Z
