cds-question@unistra.freclipsing-binary-starsinfrared-photometryvisible-astronomybroad-band-photometrykron-cousins-photometryFirst Cousins V(RI)_C_ light curves of the W UMa-type eclipsing variable star V861 Herculis are presented. The system was observed in 2000 and 2003. The light curves obtained at different epochs showed significant deviation from each other. The O'Connell effect (usually explained by spots on the surface which are responsible for variations in the intensity of the system) was about {Delta}V=0.05mag in 2000 but it vanished in 2003 (except the night of February 22/23, 2003 when we observed a small O'Connell effect ({Delta}V=0.020)). Further peculiarities of the light curves are also discussed.2004A&A...417..745Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/417/745CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/417/745https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/417/745http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/417/745https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/417/745https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/417/745http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/417/745GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/A+A/417/745/imagV861 Her Cousins I band differential magnituderecnoRecord number assigned by the VizieR team.
