Scientific paper

Twenty-six hours of new high-speed photometric observations of HD 134214 obtained in 1990 and 13 hours obtained in 1985 from both the South African Astronomical Observatory and Lowell Observatory are presented. This star seems to pulsate with only on detectable frequency with a semiamplitude of A(B) = 3.3 mmag. However, the 1985 data cannot be phased together with a single frequency, indicating that unknown complexities affect the light variations. HD 134214 is found to be an excellent candidate star in which to search for evolutionary frequency change.
