Using an unbiased statistical approach we construct a phenomenological model of solar wind -- magnetosphere interaction. This model allows measuring relative geoeffectiveness of different physical parameters, uncovering some empirical dependencies, accurately predicting the geomagnetic activity up to 3 hours ahead, and estimating the geomagnetic activity up to 9 hours ahead. For 1-hour forecast we have linear correlation LC = 0.987 and prediction efficiency PE = 0.975. For 3-hour forecast we have LC = 0.906 and PE = 0.899. For 9-hour forecast we have LC = 0.820 and PE = 0.711.
