EUHFORIA predictions at Earth for the 7 January 2014 CME. (a) Radial speed, (b) Proton number density. Cone and spheroidal model results are shown in teal and violet, respectively. As a reference, ambient solar wind model results are plotted in gray. Real measurements from Wind are shown in black. Vertical dashed lines mark the CME arrival time in the two EUHFORIA runs and in Wind observations. The CME impact speed and density in EUHFORIA runs is marked by the dots.
