cds-question@unistra.froccultationastrometryWe have completed a search for candidates for stellar occultations by Triton over the years 1995-1999 CCD strip scan images provided star positions in the relevant sky area to a depth of about 17.5Rmag. Over this time period, we find that Triton passes within 1.0arcsec of 75 stars. Appulses with geocentric minimum separations of less than 0.35arcsec will result in stellar occultations, but further astrometry and photometry is necessary to refine individual predictions for identification of actual occultations. Finder charts are included to aid in further studies and prediction refinement. The two most promising potential occultations, Tr176 and Tr180, occur in 1997.1995AJ....109.1352Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/109/1352CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/104/862 : Stellar occultation candidates (McDonald+ 1992)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/109/1352https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/109/1352http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/109/1352https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/109/1352https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/109/1352http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/109/1352GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/109/1352/table2 (Possible occultations by Triton)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/109/1352/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/109/1352/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/109/1352/table2?GETtext/xml+votable180.050000true296.51084167-20.646961110.0055555555555555566/48745-48748 48781-48783 48787-48790 48792 48800-48802 48804https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/109/1352?format=asciiOpticaldefaultJ/AJ/109/1352/table2Possible occultations by TritonrecnoRecord number assigned by the VizieR team.
