Snapshot of the EUHFORIA simulations for Case 1 (a and b), Case 2 (c and d), and Case 3 (e and f) for 2013 March 16 at 06:44 UT. The top row shows the radial solar wind speed, and the bottom row shows the scaled number density in the equatorial plane. White, red, and black arrows point at the approximate position of the First, Second, and Main CMEs (respectively). Dashed lines correspond to the magnetic field line connection from the E15, Earth, and W15 positions, backtracked to 0.1 au. The temporal evolution for (a), (c), and (e) are available as an online movie.
