Abstract: 
Multisite photoelectric V photometry of the delta-Scuti star HR 729 was obtained during 1988 November on three continents at four observatories. With single-frequency Fourier and multiple-frequency least squares analysis six pulsation frequencies were found: 14.79, 13.20, 17.40, 19.85, 15.41, and 13.73 cycles d-1. This six-frequency solution fits the observation to +/- 0.m0033 per single measurement and leaves only noise in the power spectrum of HR 729. The corresponding Q values of 0.023 to 0.035 days indicate a complex mixture of p modes with different 1 values.
