Very intense geomagnetic storms: Solar sources, characteristics and cycle distribution
We revisit previous studies in which the characteristics of the solar and interplanetary sources of intense geomagnetic storms have been discussed. We consider the very intense geomagnetic storms that occurred during Solar Cycle 23 by setting a value of Dst min <-200 nT as threshold. We have...
