Abstract
Basing on recent and old photoelectric times of minimum, a new slightly longer period of the apsidal motion for an eclipsing binary PV Cas has been obtained. A difference between observed and theoretical periods of the apsidal motion estimated on the base of Claret and Gimenez models growed up to 30 years is found.
