Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 237 Publicado el 2200Z a las 25 Aug 2021IA. Análisis de regiones solares activas y de actividad desde 24-2100Z hasta 25-2100Z 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
25/0124Z from Region 2860 (S27E28). 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 days one, two, and three (26 Aug,
27 Aug, 28 Aug).
IIA. Resumen de la actividad geofísica 24-2100Z a 25-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 406 km/s at 25/0050Z. Total IMF reached 11
nT at 25/0402Z. The maximum southward component of Bz reached -8 nT at
25/0402Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 125 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to active levels on days one, two, and three (26 Aug, 27
Aug, 28 Aug).
