[PEM12-09] Propagation of powerful CMEs occurred in early September 2017
Keywords:CMEs, shocks, solar flares
We investigated the propagation process of these CMEs using SUSANOO-CME, 3D MHD simulation of inner heliosphere (Shiota & Kataoka 2016). We chose 6 powerful CMEs including 3 halo CMEs and input these CMEs to the MHD simulation. We performed several cases of the MHD simulation changing the parameters of input CMEs and found that the shock of the second halo CME associated with the X9.3 flare compress and enhance the southward magnetic field in the ejecta of the first halo CME. The results also imply that the strong compression of the CME ejecta needed a strong shock propagating near the head-on direction and that the second CME experienced strong eastward deflection (toward to the Earth direction). We will present more detailed interaction processes these successive CMEs.
