Informe actividad solar
Informe de actividad Solar-Geofísica 2025 May 28 2200 UTCPreparado por NOAA © SWPC y procesado por SpaceWeatherLive.com
Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 148 Publicado el 2200Z a las 28 May 2025IA. Análisis de regiones solares activas y de actividad desde 27-2100Z hasta 28-2100Z Solar activity has been at low levels for the past 24 hours.
There are currently 8 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 and a slight chance for an X-class flare on
days one, two, and three (29 May, 30 May, 31 May).
IIA. Resumen de la actividad geofísica 27-2100Z a 28-2100Z
The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 648 km/s at 28/0246Z. Total IMF reached 18
nT at 28/2040Z. The maximum southward component of Bz reached -9 nT at
27/2102Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 416 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 May, 30
May) and quiet to active levels on day three (31 May). Protons have a
slight chance of crossing threshold on days one, two, and three (29 May,
30 May, 31 May).
