Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 115 Publicado el 2200Z a las 25 Apr 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 C2 event observed at
25/0135Z from Region 2816 (S22W65). There are currently 4 numbered
sunspot regions on the disk.
IB. Pronóstico de la actividad solar
Solar activity is likely to be low with a
slight chance for an M-class flare on days one, two, and three (26 Apr,
27 Apr, 28 Apr).
IIA. Resumen de la actividad geofísica 24-2100Z a 25-2100Z
The geomagnetic
field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 503 km/s at 25/2051Z. Total IMF
reached 10 nT at 24/2318Z. The maximum southward component of Bz reached
-9 nT at 24/2349Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 3082 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to active levels on day one (26 Apr) and quiet levels on
days two and three (27 Apr, 28 Apr).
