cds-question@unistra.frIn 2003-2004, we obtained 115 new observations of Phoebe, the 9th Saturnian faint satellite (visual magnitude of about 16.5). We used a large CCD detector (2048 x2048 pixels) mounted on the 1.56m astrometric reflector at the Sheshan Station, near Shanghai. In our reduction, an up-to-date catalogue of stars, UCAC2 (Zacharias et al., 2004, Cat. <I/289>), was chosen to ensure a proper astrometric calibration. A comparison of our observations to three recently available, high quality ephemerides, including the JPL SAT185 by Jacobson (SAT185, JPL satellite ephemeris), has shown that most of our observed positions of Phoebe present an accuracy of some tens of mas, which appears to be a very high level for such a faint satellite.2006A&A...454..379Qhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/454/379CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/391/767 : CCD observations of Phoebe in 1998-1999 (Fienga+, 2002)J/A+AS/139/305 : Position of Saturn's satellites (1982-1988) (Veiga+, 1999)J/A+AS/121/65 : 1990-1994 Saturn's satellites astrometry (Harper+ 1997)J/A+AS/136/257 : Saturn's satellites in 1995/97 (Harper+ 1999)J/A+A/422/377 : 1997-2000 Saturn's satellites astrometry (Qiao+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/454/379https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/454/379http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/454/379https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/454/379https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/454/379http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/454/379GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/454/379/phoebe (CCD astrometric observations in 2003-2004)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/454/379/phoebe?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/454/379/phoebe?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/454/379/phoebe?GETtext/xml+votable180.050000true102.28502416722.1737208330.0055555555555555566/23991 24006 24009 24011https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/454/379?format=asciidefaultJ/A+A/454/379/phoebeCCD astrometric observations in 2003-2004recnoRecord number assigned by the VizieR team.
