Informe de actividad Solar-Geofísica 2025 Feb 03 2200 UTCPreparado por NOAA © SWPC y procesado por SpaceWeatherLive.com
Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 34 Publicado el 2200Z a las 03 Feb 2025IA. Análisis de regiones solares activas y de actividad desde 02-2100Z hasta 03-2100Z Solar activity has been at high levels for the past 24 hours.
The largest solar event of the period was a M8 event observed at
03/0358Z from Region 3981 (N05E09). There are currently 8 numbered
sunspot regions on the disk.
IB. Pronóstico de la actividad solar
Solar activity is expected to be moderate
with a slight chance for an X-class flare on days one, two, and three
(04 Feb, 05 Feb, 06 Feb).
IIA. Resumen de la actividad geofísica 02-2100Z a 03-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 658 km/s at 03/0714Z. Total IMF reached 11 nT at
03/0212Z. The maximum southward component of Bz reached -4 nT at
03/2041Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 226 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to active levels on day one (04 Feb), quiet to unsettled
levels on day two (05 Feb) and quiet levels on day three (06 Feb).
Protons have a slight chance of crossing threshold on days one, two, and
three (04 Feb, 05 Feb, 06 Feb).
