Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 111 Publicado el 2200Z a las 21 Apr 2023IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z 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
20/2230Z from Region 3281 (S22W22). There are currently 7 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 (22 Apr, 23 Apr,
24 Apr).
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 514 km/s at 21/2036Z. Total IMF reached 6
nT at 21/1836Z. The maximum southward component of Bz reached -6 nT at
21/1815Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 131 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to active levels on days one and two (22 Apr, 23 Apr) and
quiet to unsettled levels on day three (24 Apr).
