ADC_Keywords: Stars, variable ; Photometry, UBVRI ; Photometry, CCD Abstract: We have obtained the first UBV(RI)C photoelectric light curves of the recently discovered eclipsing binary BD+66 1663 = GSC 4479 412 (P=7.04d, V=10.14). We have derived relative and absolute parameters of the binary, and analyzed the interstellar extinction towards the object. Though the star is located in the field of the young open cluster Be 59, we demonstrate that it is not a member. Description: We observed the star on six nights during the Summer and Autumn of 2008 at the Stara Lesna Observatory of the Slovak Academy of Sciences, at an altitude of 860m above the sea level.
