Informe actividad solar
Informe de actividad Solar-Geofísica 2025 Jun 04 2200 UTCPreparado por NOAA © SWPC y procesado por SpaceWeatherLive.com
Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 155 Publicado el 2200Z a las 04 Jun 2025IA. Análisis de regiones solares activas y de actividad desde 03-2100Z hasta 04-2100Z Solar activity has been at low levels for the past 24 hours.
There are currently 5 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 (05 Jun, 06 Jun, 07 Jun).
IIA. Resumen de la actividad geofísica 03-2100Z a 04-2100Z
The geomagnetic
field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 834 km/s at 04/1826Z. Total IMF
reached 15 nT at 04/1356Z. The maximum southward component of Bz reached
-12 nT at 04/1445Z. Electrons greater than 2 MeV at geosynchronous
orbit reached a peak level of 3973 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at unsettled to major storm levels on day one (05 Jun), quiet to
active levels on day two (06 Jun) and quiet to minor storm levels on day
three (07 Jun). Protons have a slight chance of crossing threshold on
days one, two, and three (05 Jun, 06 Jun, 07 Jun).
