Example of forecasts obtained with the LSTM-NN model and the linear model during two geomagnetic storms, the first one (left-hand side) being an ICME-driven storm and the second one being a SIR-driven storm (right-hand side). Four different forecast horizons were used (3, 6, 12 and 24 h). The value of Ca used for the binary classification is the blue dotted line, given as a landmark. For each prediction, the corresponding TDM value is given (the TDM values for the baseline forecasts are given in brackets).
