The non-radial pulsating star, 53 Persei, has been observed for the last four years by the Four-College Consortium Automatic Photoelectric Telescope (APT) on Mt.Hopkins. After elimination of observations not passing the various observational checks which have been devised to eliminate APT observations obtained under non-photometric conditions, we have 737 data points obtained on 243 nights. Our analysis of these observations shows that the two frequencies (0.46 c/d and 0.59 c/d) identified by Smith, et. al. (Ap. J. 282, 226, 1984) and confirmed by Huang, et. al. (Ap. J. 431 850, 1994) are present. Additionally,.there is a third term with a frequency of 0.47 c/d present in the entire data set as well as each of the four seasons analyzed individually. This work has been supported in part by NSF grants AST86-16362, AST91- 15114, and USE-9156184 to the College of Charleston.
