abstract = "In time-distance helioseismology the travel time of the acoustic waves between different points on the solar surface is measured to infer the local structure and properties of the subsurface layers of the Sun. The presence of the magnetic canopy in the solar atmosphere is expected to modify the behavior of the acoustic waves. The travel time changes due to the atmospheric magnetic field are evaluated theoretically. The uniform magnetic field in the atmosphere shortens the travel time of the acoustic waves due to enhanced rigidity of the interface where the waves are reflected. This effect increases rapidly with increasing frequency and harmonic degree. The effect of the magnetic field on the acoustic wave travel time is compared with the corresponding effect of large-scale sub-surface flows. It is suggested to use the time-distance analysis as a diagnostic tool in determining the local properties of the Sun's atmospheric magnetic field.",
