Our observations were performed in the period from August 2004 to November 2021 with three telescopes and seven different types of CCD cameras. Photometric observations, especially concerning the long-term behavior of the stars, are missing in the literature. We present the first photometric monitoring covering 17 years. Our data indicate that the variability of both stars is typical for classical T Tauri stars.2022BlgAJ..37...54Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/BAJ/37.54CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/556/A60 : BVRI observations of the FUor star V582 AurJ/A+A/568/A49 : Pre-main sequence stars long term phot.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 Photometry of YSOs (Ibryamov+ 2015)J/other/BAJ/22.3 : BVRI photometry of 5 PMS stars (Ibryamov+, 2015)J/other/BAJ/24.62 : BVRI Photometry of 14 PMS stars (Ibryamov+, 2016)J/other/RAA/17.20 : V977 Cep & V982 Cep long-term photometry (Ibryamov+ 2017)J/other/PASA/35.7 : Long-term BVRI photometry of V2492 Cygni (Ibryamov+ 2018)J/other/BAJ/29.10 : Long-term BVRI photometry of V1704 Cygni (Ibryamov+ 2018)J/other/RAA/18.137 : Long-term BVRI phot. of 15 PMS stars (Ibryamov+, 2018)J/other/Ser/199.39 : Long-Term Photometry of five PMS stars (Semkov+, 2019)J/other/Ser/202.31 : Long-term BVRI photometry of V900 Mon (Semkov+, 2021)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/BAJ/37.54https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/BAJ/37.54http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/BAJ/37.54https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/BAJ/37.54https://vizier.iucaa.in/viz-bin/votable?-source=J/other/BAJ/37.54http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/BAJ/37.54GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/BAJ/37.54/stars (List of studied stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/BAJ/37.54/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/other/BAJ/37.54/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/BAJ/37.54/stars?GETtext/xml+votable180.050000true86.5787083-0.09392220.0055555555555555566/228732.367228618189496e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/BAJ/37.54?format=asciiOpticalInfrareddefaultJ/other/BAJ/37.54/starsList of studied starsrecnoRecord number assigned by the VizieR team.
