dc.description.abstract	We present photometric observations of four stars that are optical counterparts of soft X-ray/EUV sources, namely 1ES 0829+15.9, 1ES0920-13.6, 2RE J110159+223509 and 1ES 1737+61.2. We have discovered periodic variability in two of the stars, viz., MCC 527 (1ES 0829+15.9; Period = 0d :828 0:0047) and HD 81032 (1ES 0920-13.6; Period = ~ 57:02 0:560 days). HD 95559 (2RE J110159+223509) is found to show a period of 3d . HD 160934 (1ES1737+61.2) also shows photometric variability but needs to be monitored further for finding its period. These stars most likely belong to the class of chromospherically active stars.	en
