We present the results of the numerical simulations of wavepropagation using the equations of ideal magnetohydrodynamics (MHD),utilizing a TVD scheme with an approximate Riemann solver in 1D 12 ,applied to the Moreton event registered on December 6th, 2006 with theHASTA telescope. We use the physical parameters that characterize thewave observed in the center of the H-alpha line (656.3 nm) such as thevelocity, the direction of propagation and the probable event of triggering,in order to adjust the physical magnitudes of the plasma in which thewaves propagate and of the initial firing mechanism. Finally we discusson the probable MHD waves responsible for the analyzed Moreton event.
