Scientific paper

HD 163151 is discovered to be a new variable as a part of a W UMa system. In this paper we present complete uvby light curves. Additional Crawford H_β and Johnson BV data are also obtained. A detailed photometric analysis based on these observations is presented using the WD code. Several tests have been carried out concerning mass ratio and effective temperatures. The best fitting was achieved with q = 0.27 and T_1=6450 K (fixed) and T_2 = 6130 K. Moreover, the light curves show evidences of spots in one of the components. Tables 2 to 5 will be accessible only in electronic form at the CDS
