field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 489 km/s at 21/2148Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 15548 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to active levels on day one (23 Apr), quiet to unsettled
levels on day two (24 Apr) and quiet to major storm levels on day three
