We present ground-based photometry of the stellar syzygy of KIC 4150611. KIC 4150611 is a quintuple-star system, composed of a pulsating δ-Sct A-star, a pair of eclipsing G-stars, and another pair of eclipsing K-stars. The Kepmag of the system is 7.9, and the pair of G-type stars have an orbital period of 8.6 d with the K-type dwarfs having a 1.5 d orbital period. The A-star has a period of 94 days. We utilized the Kepler data to predict the occurrence of a syzygy of the A-star and the G-stars in the summer of 2011, which we then observed with BVI CCD photometry at Mt. Laguna Observatory. These data supply additional constraints on the temperatures of the eclipsing stars.
