In situ measured values of the magnetic field components, dynamic pressure, temperature, and speed of the solar wind (top to bottom) taken from the OMNI database (black line). Also plotted are simulation data in the eruption + stealth (red line) and double eruption (blue line) cases propagated in the slow wind and taken at 1 AU. The green highlighted area approximately delimits the ICME. The dates on the X axis are from the year 2009.
