Description
Summary:CCD observations of times of minimum light of IQ Per with apsidal motion were made in VR bandpasses for four nights from November to December, 2002. From the observations four times of minimum light were determined. All times of minimum light collected from literatures, including ours, were analyzed to determine the apsidal motion parameters of IQ per. The sidereal and apsidal motion periods were calculated to be 0.035 s and 0.2 y slightly longer than those of Değirmenci (1997), respectively. The apsidal motion parameters of IQ Per derived in this paper show good agreement with Değirmenci's values. Our results support his internal density constant of bar{k}2obs = 0.0038 for IQ Per and 5 % accuracy of agreement between the observed and modelled values of the apsidal motion constant.
