Informe actividad solar
Informe de actividad Solar-Geofísica 2025 Feb 09 2200 UTCPreparado por NOAA © SWPC y procesado por SpaceWeatherLive.com
Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 40 Publicado el 2200Z a las 09 Feb 2025IA. Análisis de regiones solares activas y de actividad desde 08-2100Z hasta 09-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C4 event observed at
09/0101Z from Region 3977 (N18W96). There are currently 11 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 and two (10 Feb,
11 Feb) and expected to be low with a chance for M-class flares on day
three (12 Feb).
IIA. Resumen de la actividad geofísica 08-2100Z a 09-2100Z
The geomagnetic
field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 585 km/s at 09/2053Z. Total IMF
reached 22 nT at 09/1138Z. The maximum southward component of Bz reached
-16 nT at 09/1308Z. Electrons greater than 2 MeV at geosynchronous
orbit reached a peak level of 336 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at unsettled to minor storm levels on day one (10 Feb), unsettled
to active levels on day two (11 Feb) and quiet to active levels on day
three (12 Feb). Protons greater than 10 Mev have a slight chance of
crossing threshold on days one and two (10 Feb, 11 Feb).
