Scientific paper

The results are reported of six nights of V-band observations of the newly discovered Delta Scuti variable HD 127759 during April 3-21, 1991 and its Stromgren uvby(beta) photometry. The period analysis indicates that HD 127759 is a single-sine frequency-dominant pulsation variable with a frequency of 14.78626 cycle/d and an amplitude of 0.0199 m. The times of maximum are given. The star is located at the blue edge of the Delta Scuti variable instability strip, with T(eff) about 8400 K and M(V) about 0.93 m.
