An interesting interaction between the near Earth CMEs and the geomagnetic field leads to some complex results also. Googling Carrington Event will give some interesting details. The geomagnetic and geoelectric field monitoring at observatories of CME interaction and associated earth electrical currents is fascinating.
Is there any numeric code that will model the Newtonian trajectory and CME geometry given input velocity and mass parameters? These are CME velocity and mass parameters estimated now and I’ve seen Goddard NASA laboratory animations which show CME magnetohydrodynamics (?) combined with the estimated interplanetary trajectories and CME topology and always wondered if there was, for example, accessible MATLAB or python codes available to create such estimates. The NASA animations are found on YouTube.
