Informe actividad solar
Informe de actividad Solar-Geofísica 2021 Dec 23 2200 UTCPreparado por NOAA © SWPC y procesado por SpaceWeatherLive.com
Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 357 Publicado el 2200Z a las 23 Dec 2021IA. Análisis de regiones solares activas y de actividad desde 22-2100Z hasta 23-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C2 event observed at
23/0930Z from Region 2907 (S22W65). There are currently 9 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 (24 Dec, 25 Dec, 26 Dec).
IIA. Resumen de la actividad geofísica 22-2100Z a 23-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 585 km/s at 23/0316Z. Total IMF reached 5 nT at
23/0717Z. The maximum southward component of Bz reached -3 nT at
23/1739Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 2410 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to minor storm levels on day one (24 Dec) and quiet to
unsettled levels on days two and three (25 Dec, 26 Dec). Protons have a
slight chance of crossing threshold on days one, two, and three (24 Dec,
25 Dec, 26 Dec).
