## [76.19] A Second Period for V567 Ophiuchi

L.R. Schwendiman, E.G. Hintz (Brigham Young University)

Using the David Derrick Telescope of the Orson Pratt Observatory at Brigham Young University, eight new time of maximum light were obtained for the \delta Scuti variable V567 Ophiuchi. These data agree with the formerly published primary period of 0.149 days. Powell (1990) suggested the existence of a secondary period for this \delta Scuti star. The high temporal density CCD observations acquired confirm the existence of, and have been used to obtain, a value for this secondary period. The times of maximum light and Fourier analysis of the light curve will be reported.

We wish to thank the BYU Department of Physics & Astronomy for their support of this research.
