Informe actividad solar
Informe de actividad Solar-Geofísica 2025 Feb 22 2200 UTCPreparado por NOAA © SWPC y procesado por SpaceWeatherLive.com
Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 53 Publicado el 2200Z a las 22 Feb 2025IA. Análisis de regiones solares activas y de actividad desde 21-2100Z hasta 22-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C8 event observed at
22/0306Z from Region 4001 (N24W76). There are currently 13 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 (23 Feb, 24 Feb, 25 Feb).
IIA. Resumen de la actividad geofísica 21-2100Z a 22-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 497 km/s at 22/0136Z. Total IMF reached 7
nT at 22/1608Z. The maximum southward component of Bz reached -5 nT at
22/2000Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 382 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet levels on days one and three (23 Feb, 25 Feb) and quiet
to unsettled levels on day two (24 Feb). Protons have a slight chance of
crossing threshold on days one, two, and three (23 Feb, 24 Feb, 25 Feb).
