Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 108 Publicado el 2200Z a las 18 Apr 2023IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C4 event observed at
18/1529Z from Region 3280 (S08W94). 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
days one, two, and three (19 Apr, 20 Apr, 21 Apr).
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 624 km/s at 18/2033Z. Total IMF reached 19
nT at 18/1612Z. The maximum southward component of Bz reached -16 nT at
18/1549Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 198 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to minor storm levels on day one (19 Apr), unsettled to
minor storm levels on day two (20 Apr) and quiet to active levels on day
three (21 Apr).
