cds-question@unistra.frsolar-systemsolar-system-planetsastrometryPuck, a faint satellite very close to Uranus' planet, was discovered by Voyager 2 Spacecraft images in 1986. Ever since then, few observations from Earth have been made. This prompted us to start a program of systematic observations of this satellite with the 1.6m telescope at the Laboratorio Nacional de Astrofisica/MCT (Itajuba, Brazil). The success of the observations is mainly due to the use of a Coronagraph developed at Observatorio Nacional/MCT (Rio de Janeiro, Brazil). This article presents astrometric positions obtained from Earth observations of Puck and of the five major Uranian satellites for four nights in 2004. Those positions are compared to the theoretically calculated positions from JPL Development Ephemeris. For Puck, the root mean square (rms) of the mean residual was found to be 84 milliarcseconds (mas). The stars' USNO-A2.0 catalog (<I/252>) was used as a reference system for the astrometric calibration.2006A&A...454..683Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/454/683CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/252 : The USNO-A2.0 Catalogue (Monet+ 1998)J/A+A/391/775 : Uranian satellites in 1995/97 (Shen+, 2002)J/A+AS/138/247 : Uranian satellites 1995-1998 (Veiga+, 1999)J/A+AS/130/77 : Astrometry of Satellites of Uranus (Jones+ 1998)J/A+AS/113/557 : Uranian satellites (Veiga+, 1995)J/A+AS/107/559 : Position of Uranian satellites (Veiga+, 1994)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/454/683https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/454/683http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/454/683https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/454/683https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/454/683http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/454/683GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/454/683/table1 (Topocentric observed positions of eight satellites of Uranus)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/454/683/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/454/683/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/454/683/table1?GETtext/xml+votable180.050000true337.1828225-10.4035270.0055555555555555566/18494-18495https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/454/683?format=asciidefaultJ/A+A/454/683/table1Topocentric observed positions of eight satellites of UranusrecnoRecord number assigned by the VizieR team.
