Add to ORKGUBV observations of VV Cep were made in 1988-1992 as a part of the Ten-year Observing Program for Long Period Eclipsing Binary Stars (1982-1992) at Yonsei University Observatory. In addition to these the observations in the longer passbands in R and I are also made in the 1991-1992 season at the same observatory. Atmospheric extinction coefficient by a comparison star 20 Cep for B and V each night have been deduced a linear relation, kB = 0.159 + 1.066kV. In this paper, light curves of this star in BVRI passbands for the 1991-1992 season only are presented. Two periodic light variation of both long-term and short-term are found as for 90 days, respectively
