Table 1
Overview of a selection of ICME events that were used for validation purposes. For each event, we list the geomagnetic index Dst, the detected min Bz component, the prediction value of SODA, the observed orbit decay using external density data, and finally the solution based on the predicted solar and geomagnetic indices. Remarks: (i) * refers to a combined observed solution of the ICMEs on February 1 and 3 in 2022. (ii) for the indicated event in April 2023, we used our own density estimates since no external data were available.
