                         proposed for modeling the Carrington magnetic storm. Typical slow 
                         solar wind densities (~5 cm3 ) and lower interplanetary magnetic 
                         cloud magnetic field intensities (~90 nT) can be used to explain 
                         the observed initial and main phase storm features. A second point 
                         is that the fast storm recovery may be explained by ring current 
                         losses due to electromagnetic ion cyclotron wave scattering.",
