cds-question@unistra.froccultationastrometryA search for Triton stellar occultation candidates for the period 1992-1994 has been completed with CCD strip-scanning observations. The search reached an R magnitude of about 17.4 and found 129 candidates within 1.5arcsec of Triton's ephemeris during this period. Of these events, we expect around 30 occultations to be visible from the Earth, indicating that a number of Triton occultation events should be visible from major observatories. Even the faintest of our candidate events could produce useful occultation data if observed with a large enough telescope. Our astrometric accuracy is inadequate to identify which of these appulse events will produce occultations on the Earth; further astrometry is needed to refine the predictions for positive occultation identification. To aid in selecting candidates for additional astrometric and photometric studies, we include finder charts and Earth-based visibility charts for each event.1992AJ....104..862Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/104/862CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/104/862https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/104/862http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/104/862https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/104/862https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/104/862http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/104/862GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/104/862/table2 (Possible occultations by Triton)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/104/862/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/104/862/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/104/862/table2?GETtext/xml+votable180.050000true289.63470833-21.473394440.0055555555555555566/28997-28999 29008 48119 48122-48126 48802https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/104/862?format=asciiOpticaldefaultJ/AJ/104/862/table2Possible occultations by TritonrecnoRecord number assigned by the VizieR team.
