According to the first hypothesis of the variability of the star, it is a FU Orionis candidate erupted between 1951 and 1993. During subsequent observations, the star manifests large amplitude variability interpreted as obscuration from circumstellar clouds of dust. We included V1184 Tau (CB 34V) in our target list of highly variable pre-main-sequence stars to determine the reasons for the variations in the brightness of this object. Data from BVRI photometric observations of V1184 Tau were performed in two observatories with two medium-sized and two small telescopes. Our results indicate that during periods of maximum light the star shows characteristics typical of T Tauri stars. During the observed deep minimum in brightness, however, V1184 Tau is rather similar to UX Orionis objects. The deep drop in brightness magnitude diagrams is also confirmation of obscuration from circumstellar clouds of dust as a reason for the large amplitude variability in the brightness.2015A&A...582A.113Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/582/A113CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/582/A113https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/582/A113http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/582/A113https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/582/A113https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/582/A113http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/582/A113GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/A+A/582/A113/tablePhotometric CCD observations of V1184 Tau during the period October 2000-April 2015recnoRecord number assigned by the VizieR team.
