Abstract:

The first BVRI CCD photometric observations of PY Lyrae were obtained at the Kryoneri Observatory in the summer of 2004. Five new times of minima and a new ephemeris were calculated. The light curves were analyzed with the Wilson-Devinney program, in order to derive the geometric and photometric elements of the system. A spot model was assumed in order to explain the pronounced O'Connell effect.
