Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 240 Publicado el 2200Z a las 28 Aug 2021IA. Análisis de regiones solares activas y de actividad desde 27-2100Z hasta 28-2100Z Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M4 event observed at
28/0611Z from Region 2860 (S29W10). There are currently 4 numbered
sunspot regions on the disk.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low with
a chance for M-class flares on days one, two, and three (29 Aug, 30 Aug,
31 Aug).
IIA. Resumen de la actividad geofísica 27-2100Z a 28-2100Z
The geomagnetic
field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 389 km/s at 28/1718Z. Total IMF
reached 14 nT at 27/2100Z. The maximum southward component of Bz reached
-12 nT at 27/2131Z. Electrons greater than 2 MeV at geosynchronous
orbit reached a peak level of 10655 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to minor storm levels on days one and two (29 Aug, 30
Aug) and quiet levels on day three (31 Aug).
