We present results from long-term optical photometric and spectroscopicobservations of 5 pre-main sequence stars, located in the vicinity of the bightnebula NGC 7129. We obtained UBVRI photometric observations in the fieldcentered on the star V391 Cep, north-west of the bright nebula NGC 7129. Ourmulticolor CCD observations spanned the period from February 1998 to November2016. At the time of our photometric monitoring, a total of thirteenmedium-resolution optical spectra of the stars were obtained. The results fromour photometric study show that all stars exhibit strong variability in alloptical passbands. Long-term light curves of the five stars indicate thetypical of classical T Tauri stars variations in brightness with largeamplitudes. We did not find any reliable periodicity in the brightnessvariations of all five stars. The results from spectral observations showedthat all studied stars can be classified as a classical T Tauri stars withreach emission line spectra and strong variability in the profiles andintensity of emission lines.
