We present observational evidence of modified two stream instability driven electron Bernstein and solitary waves at a quasi-perpendicular interplanetary shock. The Bernstein waves show enhanced power at harmonics of the cyclotron frequency with a broadened spectrum, consistent with the electron cyclotron drift instability. The solitary waves are obliquely polarized with respect to the magnetic field but appear parallel to the shock normal direction, consistent with the simulation results of Matsukiyo and Scholer [2006]. Strong particle heating in both the electrons and ions is observed near these waves beyond the adiabatic limit. These results may offer new insights into collisionless shock dissipation and wave-particle interactions in the solar wind.
