SDF Número 245 Publicado el 2200Z a las 02 Sep 2021IA. Análisis de regiones solares activas y de actividad desde 01-2100Z hasta 02-2100Z Solar activity has been at very low levels for the past 24
hours. There are currently 2 numbered sunspot regions on the disk.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very low
with a chance for a C-class flares on day one (03 Sep) and expected to
be very low with a slight chance for a C-class flare on days two and
three (04 Sep, 05 Sep).
