cds-question@unistra.frnovaeinfrared-photometryvisible-astronomyWide-band photometryWe present the UBV(RI)C photometry of a new dwarf nova V466 And, discovered during its superoutburst on Sept. 1.6, 2008 and classified as a WZ Sge-type object. In the first 11 days of the superoutburst, the early superhumps with the period of 0.056383d were found. In days 13-23 of the superoutburst, the ordinary superhumps with the period of 0.05713d were exposed. They were replaced by late superhumps with the period of 0.056d in days 24-33 of the superoutburst. After one month, the dwarf nova returned to its pre-outburst state. A list of known WZ Sge-type dwarf novae, including suspected ones, is presented. We determined a mean value of superhump period excess for WZ Sge-type objects as {epsilon}=0.019+/-0.003. The multicolour photometry of the field stars enables us to conclude that there is no appreciable interstellar extinction in the direction of V466 And.2010CoSka..40...19Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/CoSka/40.19CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/other/CoSka/39.43 : Nova Tri UBV(RI)c light curves (Chochol+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/CoSka/40.19https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/CoSka/40.19http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/CoSka/40.19https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/CoSka/40.19https://vizier.iucaa.in/viz-bin/votable?-source=J/other/CoSka/40.19http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/CoSka/40.19GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/other/CoSka/40.19/photUBVRcIc magnitudes of V466 And (tables7-11 of the paper)recnoRecord number assigned by the VizieR team.
