Abstract
We present a model for the propagation of coronal mass ejections (CMEs) based on the interaction of CMEs with the solar wind through aerodynamic drag. The parameters of the solar wind are calculated based on observational data of the STOP magnetograph. The CME parameters, namely, the velocity vector and the estimated density at the initial stage of propagation, can be determined from the data of patrol telescopes. In the model, we consider a CME in the form of a cloud, represented by a set of points, and we track the trajectory of the motion of each point in the heliosphere. The simulation data can be used to estimate the geoefficiency of coronal mass ejections.
