SDF Número 355 Publicado el 2200Z a las 20 Dec 2020IA. 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 days one, two, and three (21
Dec, 22 Dec, 23 Dec).
IIA. Resumen de la actividad geofísica 19-2100Z a 20-2100Z

a peak level of 227 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to active levels on day one (21 Dec), quiet to unsettled
levels on day two (22 Dec) and quiet to minor storm levels on day three
