cds-question@unistra.frseyfert-galaxiesgalaxiesspectroscopyWe present the results of optical spectral and photometric observations of the nucleus of Markarian 6 made with the 2.6-m Shajn telescope at the Crimean Astrophysical Observatory. The continuum and emission Balmer-line intensities varied by more than a factor of two during 1992-2008. The lag between the continuum and H{beta} emission-line flux variations is 21.1+/-1.9days. For the H{alpha} line the lag is about 27-days, but its uncertainty is much larger.2012MNRAS.426..416Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/426/416CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/426/416https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/426/416http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/426/416https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/426/416https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/426/416http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/426/416GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/MNRAS/426/416/table1{lambda}5170 spectral continuum, the H{beta} and H{gamma} line fluxesrecnoRecord number assigned by the VizieR team.
