Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 141 Publicado el 2200Z a las 21 May 2021IA. 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.
The largest solar event of the period was a C4 event observed at
21/1928Z from Region 2824 (N20E27). 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 chance for a C-class flares on days one, two, and three (22 May,
23 May, 24 May).
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z

field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 598 km/s at 21/0541Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 819 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to unsettled levels on day one (22 May) and quiet levels
on days two and three (23 May, 24 May).
