Description
In this talk, I will review different methods to determine a CME direction and velocity from single and multiple spacecraft remote-sensing observations. I will discuss why the assumptions of constant speed and directions and very narrow CMEs have been successful so far and why this may change in the near future as the STEREO spacecraft move farther apart.
I will finally discuss the case of successive CMEs and why fitting methods and even J-maps can only be used with extreme caution in this case.
