We report here the δ Scuti pulsation characteristics of low-amplitude oscillations of star V461 Per in the α Persei cluster. The 61 hr of high-quality light curve over seven nights have confirmed the low-amplitude oscillation characteristics of V461 Per. The amplitude spectra indicate a multiperiodic pulsation behavior, two pulsation frequencies and have been confidently identified, and three other frequencies (,, and) are probable. Explanation on the complicated frequency distribution requires a combination of both radial and nonradial modes. A preliminary comparison with models suggests that the observed modes would lie in the range of modes from high rank to. The δ Scuti variable V461 Per has almost the same and as the δ Scuti variable V459 Per in the same α Persei cluster. This suggests that it will be meaningful to have a comparison study of the two variables, and the pulsation characteristics discovered in the observations demonstrate that they share similar main frequency distribution style.
