V0842 Cep is a W UMa-type binary star that has been neglected since its discovery. We analysed the VR c I c light curves, obtained by the 1 m telescope at Weihai Observatory of Shandong University, using the Wilson-Devinney code. V0842 Cep was found to be a shallow contact binary system ( f = 8.7%)...
