cds-question@unistra.frseyfert-galaxiesvisible-astronomyWide-band photometryThe results of three-color UBV observations of rapid variability in the nucleus of the Seyfert galaxy NGC 7469 carried out in 1990-1994 are presented. The observations have been carried out during 15 different nights using the 60- and 125-cm telescopes with time resolution of 6-8min (50 hours monitoring) with the aperture of 27.5". The mean errors of one measurement are 1.8, 1.2 and 1.4% for U, B and V. The data set length during one night is from 2 up to 5h. The different nights show the variations at different level: from weak, when the standard deviation during the night exceeds the error of one measurement only by 10-20%, up to strong ones, when the standard deviation exceeds the error of the measurement by factor two.1995PAZh...21..652Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PAZh/21/652CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PAZh/21/652https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PAZh/21/652http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PAZh/21/652https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PAZh/21/652https://vizier.iucaa.in/viz-bin/votable?-source=J/PAZh/21/652http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PAZh/21/652GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/PAZh/21/652/tableUBV photometry of NGC 7469recnoRecord number assigned by the VizieR team.
