Informe actividad solar
Informe de actividad Solar-Geofísica 2025 Sep 05 2200 UTCPreparado por NOAA © SWPC y procesado por SpaceWeatherLive.com
Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 248 Publicado el 2200Z a las 05 Sep 2025IA. Análisis de regiones solares activas y de actividad desde 04-2100Z hasta 05-2100Z Solar activity has been at moderate levels for the past 24
hours. There are currently 9 numbered sunspot regions on the disk.
IB. Pronóstico de la actividad solar
Solar activity is likely to be moderate
with a slight chance for an X-class flare on day one (06 Sep) and
expected to be low with a chance for M-class flares on days two and
three (07 Sep, 08 Sep).
IIA. Resumen de la actividad geofísica 04-2100Z a 05-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 686 km/s at 04/2105Z. Total IMF reached 10
nT at 05/1945Z. The maximum southward component of Bz reached -7 nT at
05/0802Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 793 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to minor storm levels on day one (06 Sep), unsettled to
minor storm levels on day two (07 Sep) and quiet to unsettled levels on
day three (08 Sep). Protons greater than 10 Mev have a slight chance of
crossing threshold on day one (06 Sep).
