Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 199 Publicado el 2200Z a las 18 Jul 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 11 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
(19 Jul, 20 Jul, 21 Jul).
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 670 km/s at 18/0647Z. Total IMF reached 7
nT at 17/2141Z. The maximum southward component of Bz reached -5 nT at
18/1552Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 10272 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to unsettled levels on day one (19 Jul) and quiet levels
on days two and three (20 Jul, 21 Jul). Protons have a slight chance of
crossing threshold on days one, two, and three (19 Jul, 20 Jul, 21 Jul).
