Example of predicting the geomagnetic storm that occurred by CME on 20 November 2003. From top: (a) the solar wind density, (b) IMF total field, (c) IMF Bz, (d) solar wind speed, V × Bs, and (e) Dst index measured and predicted. In the bottom panel, the gray line shows the measured Dst index, the color dots indicate the value predicted 1 h at each hour, and the colored lines show predicted Dst values for 24 h with a one-hour interval.
