Scientific paper

Time resolved CCD differential photometry was carried out for the δ Scuti variable V650 Tau on fourteen nights between November and December, 1993(total 3707 points of differential B magnitudes during about 81 hours observation). By applying the Fourier analysis to the observed data, we have detected five frequencies(f_1_=377.7μHz, f_2_=197.3μHz, f_3_=292.8μHz, f_4_=333.0μHz, f_5_=214.1μHz). Among these, the amplitudes of two frequencies, f_1_ and f_2_, show some differences from the preliminary results of STEPHI network(Michel et al. 1995). The comparison of observed frequency ratios and pulsation constants with theoretical ones suggests that V650 Tau may pulsate simultaneously in two dominant radial(F, 3H) and three nonradial modes.
