Abstract

(Abstract only) The entry for V608 Cas in the 4th edition of the General Catalogue of Variable Stars (Kholopov, P. N., et al. 1985, Moscow) notes that the type (E), period (0.47 day), and photographic magnitude range (12.3–13.3) are uncertain. CCD photometry in 1997 using a 6-inch f/3.3 reflector confirms that this star is an eclipsing binary, with a Vmagnitude primary eclipse amplitude of 0.8, and a secondary eclipse amplitude of 0.6. Based on six times of minima obtained in 1997–1998, new ephemeris elements for primary minima are JDhel. = 2450769.640 + 0.470058 E.
