Abstract
Our time series analysis of V 368 Cep photometry ascertains the rotation pe riod of 2.(d)74 uniquely. The manifestations of starspot induced luminosity variations in this chromospherically active star include rapid light curve changes and differential rotation of about 3%. We conclude that the single rapidly rotating variable V 368 Cep is a high inclination Klv post T Tauri star.
