Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 362 Publicado el 2200Z a las 28 Dec 2021IA. Análisis de regiones solares activas y de actividad desde 27-2100Z hasta 28-2100Z Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M1 event observed at
28/0401Z from Region 2918 (N21W26). There are currently 5 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 on days one, two, and three (29 Dec, 30 Dec,
31 Dec).
IIA. Resumen de la actividad geofísica 27-2100Z a 28-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 551 km/s at 28/1500Z. Total IMF reached 10
nT at 28/0125Z. The maximum southward component of Bz reached -8 nT at
28/0330Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 284 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to active levels on day one (29 Dec) and quiet to
unsettled levels on days two and three (30 Dec, 31 Dec).
