cds-question@unistra.frvariable-starsvisible-astronomynarrow-band-photometryWe discuss 24yr of optical photometry of {eta} Carinae, among which new Geneva photometry made between 1994 and 1998. Various conclusions from our previous photometric studies are confirmed. The core hides a normal S Dor variable (or LBV): it shows light variations on a time scale of 1-4yr, with superimposed micro oscillations whose quasi-period indicates a temperature in the order of 22000K. Therefore, a more complicated model for {eta} Car is necessary to explain its extraordinary appearance and phenomena exhibited in the past and at present.1999A&A...343..847Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/343/847CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJS/71/983 : UV spectrum of eta Car (Viotti+ 1989)J/A+A/304/415 : uvby-Hbeta photometry of Eta Car 1992-94 (van Genderen+, 1995)J/A+A/419/215 : Emission lines of eta Car (Hartman+, 2004)J/AJ/129/2018 : RXTE scaled fluxes of eta Car (Corcoran+, 2005)J/ApJS/157/138 : UV spectrum of eta Car (Nielsen+, 2005)J/ApJS/163/173 : UV spectrum of eta Car in 2003.5 (Gull+, 2006)J/ApJS/168/289 : NUV spectrum of eta Car in 2003.5 (Nielsen+, 2007)J/A+A/493/1093 : BVRI light curves of eta Car (Fernandez-Lajus+, 2009)J/ApJS/181/473 : Eta Carinae: visible and near-IR analysis (Nielsen+, 2009)J/other/NewA/15.108 : UBVRIHalpha of eta Car in 2009 (Fernandez-Lajus+ 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/343/847https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/343/847http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/343/847https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/343/847https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/343/847http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/343/847GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/343/847/table2Eta Car Geneva photometryrecnoRecord number assigned by the VizieR team.
