IA. 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
