Informe de actividad Solar-Geofísica 2025 Feb 27 2200 UTCPreparado por NOAA © SWPC y procesado por SpaceWeatherLive.com
Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 58 Publicado el 2200Z a las 27 Feb 2025IA. Análisis de regiones solares activas y de actividad desde 26-2100Z hasta 27-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C7 event observed at
27/1236Z from Region 3998 (S14W84). There are currently 7 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 (28 Feb,
01 Mar) and expected to be low with a chance for M-class flares on day
three (02 Mar).
IIA. Resumen de la actividad geofísica 26-2100Z a 27-2100Z
The geomagnetic
field has been at quiet to major storm levels for the past 24 hours.
Solar wind speed reached a peak of 676 km/s at 27/0418Z. Total IMF
reached 14 nT at 26/2123Z. The maximum southward component of Bz reached
-11 nT at 26/2201Z. Electrons greater than 2 MeV at geosynchronous
orbit reached a peak level of 189 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at unsettled to active levels on day one (28 Feb), quiet to active
levels on day two (01 Mar) and quiet to unsettled levels on day three
(02 Mar). Protons greater than 10 Mev have a slight chance of crossing
threshold on days one and two (28 Feb, 01 Mar).
