UBV light curves of LT Del

Long-term photometric and spectroscopic observations of the yellow symbiotic star LT Del are analyzed. UBV light curves are presented. Based on the observations of 20 cycles, we have refined the orbital period of the star, P=476.0d+/-1.0d. The brightness has been found to be unstable at some orbital phases with an amplitude up to 0.3m.
