cds-question@unistra.froccultationA photographic search was conducted for stars that may be occulted by the unusual solar system object (2060) Chiron during the period from fall 1993 through summer 1996. 44 candidates were identified to a limiting V magnitude of 16, and for which the minimum appulse separation with Chiron is predicted to be less than 2.5arcsec. The successful observation of a stellar occultation by Chiron would give a direct measure of its diameter (currently estimated to be between 60 and 300km), and would help considerably in constraining Chiron's surface properties and volatile makeup. If at the time of the occultation, Chiron exhibits a significant coma, there is also the potential for measuring the optical-depth profile of the dust in its inner coma.1994AJ....107.1814Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/107/1814CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/107/1814https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/107/1814http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/107/1814https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/107/1814https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/107/1814http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/107/1814GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/107/1814/table2 (Possible occultations by Chiron)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/107/1814/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/107/1814/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/107/1814/table2?GETtext/xml+votable180.050000true151.513733335.866833330.0055555555555555566/25469 25557 25775 25786 26119 26121 26126 26146-26147 26947 26953 26955 26958-26959 26980 26982 26986 27398 27404 27406-27408 27410 27416 27427 27435 27522https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/107/1814?format=asciiOpticaldefaultJ/AJ/107/1814/table2Possible occultations by ChironStarStar namemeta.id;meta.maincharSolEl[21/166] Solar elongationdegpos.angDistanceintrecnoRecord number assigned by the VizieR team.
