Abstract:
In this communication, photoelectric elements of the eclipsing binary system XX Cas in U, B and V filters and revised colour indices have been presented. In the absence of good photoelectric observations and complete set of photoelectric elements in the literature, and in order to remove the uncertainties regarding the nature eclipses, duration of totality, if any, spectral classes of the components, apsidal motion, ellipticity and reflection effects, the UBV photometry of the system XX Cas was carried out by the author during the period December 1972 to February 1975.
