cds-question@unistra.frvariable-starsinfrared-photometryvisible-astronomyWide-band photometryCepheids, the principal distance indicators, point to the existence of two inner Galactic spiral arms in the immediate solar neighborhood (within 5kpc). However, the available Cepheids are clearly insufficient for a detailed study of the structure of these arms. Fortunately, southern-sky monitoring (the ASAS project) has led to the discovery of many new variable stars, more than one thousand of which have been identified as possible Cepheids. To improve the classification and to construct reliable light curves for new Cepheids, we have begun their regular photometric observations. Here, we present the first results: 1192 photoelectric BVIc observations were performed for 33 classicalCepheidswith the 76-cm telescope of the South-African Astronomical Observatory (SAAO, the South-African Republic) from December 2006 to January 2008.We provide tables of observations and V light and B-V and V-Ic color curves. The new observations together with ASAS-3 data have been used to improve the elements of the light variations.2009PAZh...35...44Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PAZh/35/44CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/264 : ASAS Variable Stars in Southern hemisphere (Pojmanski+, 2002-2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PAZh/35/44https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PAZh/35/44http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PAZh/35/44https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PAZh/35/44https://vizier.iucaa.in/viz-bin/votable?-source=J/PAZh/35/44http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PAZh/35/44GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PAZh/35/44/table2 (Elements of the light variations for Cepheids from the ASAS-3 catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PAZh/35/44/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/PAZh/35/44/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PAZh/35/44/table2?GETtext/xml+votable180.050000true102.1208-10.23670.0055555555555555566/20852 21672 28918 29106 29542 37339 37359 37363 37737 37747 37750 37752 37873 37921 39283 39357 39369 39381 39382 39405 39419 39771 39773 41655 41759 41780 42151 42171 42224 42264 42453 43022https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PAZh/35/44?format=asciiOpticalInfrareddefaultJ/PAZh/35/44/table2Elements of the light variations for Cepheids from the ASAS-3 catalogrecnoRecord number assigned by the VizieR team.
