Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 49 Publicado el 2200Z a las 18 Feb 2022IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z Solar activity has been at very low levels for the past 24
hours. There are currently 4 numbered sunspot regions on the disk.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very low
with a chance for a C-class flares on day one (19 Feb) and likely to be
low with a slight chance for an M-class flare on days two and three (20
Feb, 21 Feb).
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 356 km/s at 17/2203Z. Total IMF reached 11 nT at
18/1806Z. The maximum southward component of Bz reached -7 nT at
18/1726Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 4650 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to unsettled levels on day one (19 Feb), quiet to minor
storm levels on day two (20 Feb) and quiet to active levels on day three
(21 Feb).
