SDF Número 264 Publicado el 2200Z a las 21 Sep 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 C1 event observed at
21/1153Z from Region 2873 (N26W22). There are currently 3 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 and a slight chance for an M-class
flare on days one, two, and three (22 Sep, 23 Sep, 24 Sep).
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z

field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 344 km/s at 21/0539Z. Total IMF reached 9
nT at 21/1927Z. The maximum southward component of Bz reached -8 nT at
21/1927Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 174 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to unsettled levels on days one and three (22 Sep, 24
Sep) and quiet to active levels on day two (23 Sep).
