Five nights of photoelectric photometric observations through v and y filters confirm the pulsation of the Am δ Scuti variable 60 Tau. Power spectra of the light curves show multiple periods; two modes f1 = 13.0364 d−1 and f2 = 11.8521 d−1 are definitely identified. The phase differences, ϕv − ϕy, suggest that 60 Tau pulsates in low-degree modes; the pulsation constants, Q, suggest these are low overtone modes; and the frequency ratio implies that at least one mode is nonradial.
