Abstract. We present the analysis of the light curves of two BY Dra type variables V1147 Tau and V401 Vul. These two stars were observed from 104 cm Sampurnanand Telescope of Aries. For our analysis, we have also used the archival data from Hipparchus and All Sky Automated Survey(ASAS). Our period analysis shows the stars V1147 Tau and V401 Vul are periodic variable with the period of 1.5 days and 2.161 days respectively. Light curves observed at different epochs show change in minima, amplitude and shape. This indicates that the variability is due to the presence of dark spots.
