Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 49 Publicado el 2200Z a las 18 Feb 2025IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C5 event observed at
18/0108Z from Region 3990 (S09W37). There are currently 10 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 (19 Feb, 20 Feb, 21 Feb).
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 530 km/s at 18/0625Z. Total IMF reached 8
nT at 18/2053Z. The maximum southward component of Bz reached -8 nT at
18/2051Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 1394 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to unsettled levels on day one (19 Feb) and quiet levels
on days two and three (20 Feb, 21 Feb).
