Photoelectric observations of the Delta Scuti star BD + 43 deg 1894, discovered by Yamasaki et al. (1981), are reported, and the period is calculated. A total of 331 observations were made over 48 days in 1982 on 84 and 200-cm telescopes at San Pedro Martir, Mexico, and on a 91-cm telescope at Dodaira, Japan, both using a V-type filter. The period was calculated using these data plus the observations of Yamasaki et al. (1981), a total time span of 801 days. A single period of 0.098286 days is found, confirming the preliminary calculations of Yamasaki et al.; but the determination and interpretation of the M(v) and Q parameters remain problematic.
