Solar Orbiter observations on 23 July 2020 between 20:10 UT and 21:50 UT. (a) Magnetic field in the RTN coordinates. (b) Ion bulk velocity V_R component. (c) Ion bulk velocity V_T and V_N components. (d) Alfvén speed |V_A| and Alfvén velocity components (V_A, R, V_A, T, V_A, N). (e) Ion number density. (f) Plasma pressure P_p, magnetic pressure P_m, and total pressure P_tot. (g) Plasma beta β. The KH waves can be noticed between 20:45 and 21:30 UT. The vertical gray dashed lines (1)–(7) mark the boundary layer crossings corresponding to KH trailing edges. The magenta dashed-dotted lines mark times when the plasma parameters reach asymptotic values on Side 1 (20:38 UT) and Side 2 (21:29 UT) of the shear layer.
