High-speed photometric observations of HD 134214 obtained during 35 hr of observation in 1985 from Lowell Observatory and the South African Astronomical Observatory are presented. A frequency analysis of these data indicate the presence of only one frequency of oscillation in this star at fl=2.94960 ± 0.00004 mHz (P=5.650 ± 0.001 min). This is the highest frequency which is demonstrably not a harmonic of a lower frequency yet discovered in a rapidly oscillating Ap star. This frequency is above the critical frequency calculated for A star models by Shibahashi & Saio. The phase shift ∆ φ (V, B-V)= 19± 6° has been calculated for HD 134214 from simultaneous B and V observations obtained on three nights from Lowell Observatory. The interpretation of this phase shift is problematical. Mean B light observations of HD 134214 made at Lowell Observatory and the South African Astronomical Observatory give inconsistent results for the rotation period of HD 134214.
