The observations of sunspot chromosphere are presented. The authors suggest the existence of two modes of propagating waves at the chromospheric level. The connection between these modes and magnetic field topology can be inferred from the analysis of mode propagation velocity and spatial localization. Two hypotheses are tested to explain the phenomenon: “Visual pattern” and “Trans-sunspot wave”.
