                         filtering and reconstruction technique and apply this to the solar 
                         wind magnetic field components detected at the L1 Lagrange point 
                         ~0.01 AU upstream of the Earth. This filtered interplanetary 
                         magnetic field (IMF) data is fed into a model to calculate a time 
                         series which we call AE*. This model was adjusted assuming that 
                         magnetic reconnection associated with southward directed IMF Bz is 
                         the main mechanism transferring energy into the magnetosphere. The 
                         calculated AE* was compared to the observed AE index using cross 
                         correlation analysis. The results show correlations as high as 
                         0.90. Empirical removal of the high-frequency, shortwavelength 
                         Alfv{\'e}nic component in the IMF by wavelet decomposition is 
                         shown to dramatically improve the correlation between AE* and the 
                         observed AE index. It is envisioned that this AE* can be used as 
                         the main input for a model to forecast relativistic electrons in 
                         the Earth's outer radiation belts, which are delayed by ~1 to 2 
                         days from intense AE events.",
