Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 77 Publicado el 2200Z a las 18 Mar 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.
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 (19 Mar, 20 Mar, 21 Mar).
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 480 km/s at 18/1810Z. Total IMF reached 10
nT at 18/2057Z. The maximum southward component of Bz reached -7 nT at
18/1223Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 3091 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to active levels on days one and two (19 Mar, 20 Mar) and
quiet to unsettled levels on day three (21 Mar).
