cds-question@unistra.frvariable-starsx-ray-sourcesphotometryIn the course of our search for the optical identifications of ROSAT X-ray sources, we have found a highly variable object with a very unusual behavior on long time scales, rare color indices, and a high X-ray-to-optical flux ratio. We present the archival light curve from the Catalina Sky Survey, optical spectroscopy from RTT150, and time-resolved photometry from the Astrotel-Caucasus telescope. The object appears to be a magnetic cataclysmic variable (a polar) with an orbital period P=3.20h.2011PAZh...37..924Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PAZh/37/924CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PAZh/37/924https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PAZh/37/924http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PAZh/37/924https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PAZh/37/924https://vizier.iucaa.in/viz-bin/votable?-source=J/PAZh/37/924http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PAZh/37/924GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapX-rayOpticaldefaultJ/PAZh/37/924/table3Astrotel-Caucasus photometry of RX J0733.7+2619recnoRecord number assigned by the VizieR team.
