We obtained UBVRI photometric observations in the field centered on the star V391 Cep, north-west of the bright nebula NGC 7129. Our multicolor CCD observations spanned the period from February 1998 to November 2016. At the time of our photometric monitoring, a total of thirteen medium-resolution optical spectra of the stars were obtained. The results from our photometric study show that all stars exhibit strong variability in all optical passbands. Long-term light curves of the five stars indicate the typical classical T Tauri star variations in brightness with large amplitudes. We did not find any reliable periodicity in the brightness variations of all five stars. The results from spectral observations showed that all studied stars can be classified as classical T Tauri stars with rich emission line spectra and strong variability in profiles and intensity of emission lines.2019SerAJ.199...39Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/Ser/199.39CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/556/A60 : BVRI observ. of the FUor star V582 Aur (Semkov+, 2013)J/other/RAA/14.1264 : V350 Cep UBVRI long-term photometry (Ibryamov+, 2014)J/other/PASA/32.11 : Long-term UBVRI photometry of GM Cep (Semkov+, 2015)J/other/PASA/32.21 : Long-Term Multicolour Phot. of YSOs (Ibryamov+, 2015)J/other/BAJ/24.62 : BVRI Photometry of 14 PMS stars (Ibryamov+, 2016)J/other/RAA/17.20 : V977 Cep and V982 Cep long-term phot.
