چکیده
Shock processes occur naturally in various astrophysical and space situations, the most common such as supernova explosions and solar winds in the interplanetary medium. MHD Shock Waves and discontinuities are often observed in the solar wind. We studied a strong shock wave event on 7 June 2014, during a solar maximum. The properties of forward shock are investigated and all physical parameters of interplanetary shock analyzed. To determine the propagation speed of the shock a full numerical solution of shock adiabatic equation is carried out. The upstream parameters, such as Alfven velocity and sound speed are calculated, and also the angle between the upstream magnetic field direction and the shock normal is estimated.

Abstract
Shock processes occur naturally in various astrophysical and space situations, the most common such as supernova explosions and solar winds in the interplanetary medium. MHD Shock Waves and discontinuities are often observed in the solar wind. We studied a strong shock wave event on 7 June 2014, during a solar maximum. The properties of forward shock are investigated and all physical parameters of interplanetary shock analyzed. To determine the propagation speed of the shock a full numerical solution of shock adiabatic equation is carried out. The upstream parameters, such as Alfven velocity and sound speed are calculated, and also the angle between the upstream magnetic field direction and the shock normal is estimated.
