Informe actividad solar
Informe de actividad Solar-Geofísica 2025 Aug 27 2200 UTCPreparado por NOAA © SWPC y procesado por SpaceWeatherLive.com
Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 239 Publicado el 2200Z a las 27 Aug 2025IA. Análisis de regiones solares activas y de actividad desde 26-2100Z hasta 27-2100Z Solar activity has been at low levels for the past 24 hours.
There are currently 13 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 days one, two, and three
(28 Aug, 29 Aug, 30 Aug).
IIA. Resumen de la actividad geofísica 26-2100Z a 27-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 421 km/s at 26/2134Z. Total IMF reached 8
nT at 27/0351Z. The maximum southward component of Bz reached -7 nT at
27/1101Z. Protons greater than 10 MeV at geosynchronous orbit reached a
peak level of 13 pfu at 27/0740Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 349 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (28 Aug, 29 Aug)
and quiet levels on day three (30 Aug). Protons have a chance of
crossing threshold on day one (28 Aug) and have a slight chance of
crossing threshold on days two and three (29 Aug, 30 Aug).
