Informe actividad solar
Informe de actividad Solar-Geofísica 2021 Dec 24 2200 UTCPreparado por NOAA © SWPC y procesado por SpaceWeatherLive.com
Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 358 Publicado el 2200Z a las 24 Dec 2021IA. Análisis de regiones solares activas y de actividad desde 23-2100Z hasta 24-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C7 event observed at
24/0342Z from Region 2917 (S27E05). There are currently 8 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
day one (25 Dec) and expected to be low with a slight chance for an
M-class flare on day two (26 Dec) and expected to be very low with a
chance for a C-class flares on day three (27 Dec).
IIA. Resumen de la actividad geofísica 23-2100Z a 24-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 525 km/s at 24/0131Z. Total IMF reached 5 nT at
24/1847Z. The maximum southward component of Bz reached -4 nT at
24/1928Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 2017 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to active levels on days one and two (25 Dec, 26 Dec) and
quiet to unsettled levels on day three (27 Dec). Protons greater than 10
Mev have a slight chance of crossing threshold on day one (25 Dec).
