Informe actividad solar
Informe de actividad Solar-Geofísica 2023 Feb 25 2200 UTCPreparado por NOAA © SWPC y procesado por SpaceWeatherLive.com
Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 56 Publicado el 2200Z a las 25 Feb 2023IA. Análisis de regiones solares activas y de actividad desde 24-2100Z hasta 25-2100Z Solar activity has been at high levels for the past 24 hours.
The largest solar event of the period was a M6 event observed at
25/1944Z from Region 3229 (N25W46). There are currently 6 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, two, and three
(26 Feb, 27 Feb, 28 Feb).
IIA. Resumen de la actividad geofísica 24-2100Z a 25-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 488 km/s at 24/2252Z. Total IMF reached 11
nT at 25/2055Z. The maximum southward component of Bz reached -8 nT at
25/1746Z. Protons greater than 10 MeV at geosynchronous orbit reached a
peak level of 7 pfu at 25/2100Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 966 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to minor storm levels on day one (26 Feb), unsettled to
major storm levels on day two (27 Feb) and unsettled to minor storm
levels on day three (28 Feb). Protons are expected to be above threshold
as a 10 MeV proton event is in progress.
