Informe actividad solar
Informe de actividad Solar-Geofísica 2025 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 2025IA. Análisis de regiones solares activas y de actividad desde 24-2100Z hasta 25-2100Z Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M3 event observed at
24/2302Z. There are currently 9 numbered sunspot regions on the disk.
IB. Pronóstico de la actividad solar
Solar activity is likely to be moderate
with a chance for X-class flares 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 433 km/s at 25/0054Z. Total IMF reached 17
nT at 24/2235Z. The maximum southward component of Bz reached -10 nT at
25/1842Z. Protons greater than 10 MeV at geosynchronous orbit reached a
peak level of 37 pfu at 25/0240Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 209 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (26 Feb, 27 Feb)
and unsettled to active levels on day three (28 Feb). Protons are
expected to cross threshold on day one (26 Feb), are likely to cross
threshold on day two (27 Feb) and have a chance of crossing threshold on
day three (28 Feb).
