cds-question@unistra.frsolar-systemasteroidsinfrared-photometryvisible-astronomybroad-band-photometryThe five major Uranian satellites (Ariel, Umbriel, Titania, Oberon, and Miranda) were observed by a 1.56m telescope at Sheshan Station of Shanghai Astronomical Observatory during 2008-2014 and a total of 1915 positions of these five satellites were presented in this paper. Since all five satellites are close to Uranus, their positions are affected by the uneven background, which is caused by the halo of Uranus. The median filtering method is used to remove the influence of the halo of the bright Uranus, which also made the rate of target detection increase by 30%-100%, especially for Miranda. Gaia EDR3 is used as the reference catalog when calculating positions of the five satellites. A comparison between our positions with the theoretical positions of the satellites from Institut de mecanique celeste et de calcul des ephemerides (IMCCE) is given. Such precise positions over a long time will be very helpful to improve the orbit parameters of the five major Uranian satellites.2022AJ....164...37Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/164/37CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/350 : Gaia EDR3 (Gaia Collaboration, 2020)J/A+AS/113/557 : Uranian satellites (Veiga+, 1995)J/A+A/383/296 : Saturnian Satellites positions (1996-2000) (Peng+, 2002)J/A+A/391/775 : Uranian satellites in 1995/97 (Shen+, 2002)J/A+A/582/A8 : Astrometry of the main satellites of Uranus (Camargo+, 2015)J/other/OAP/29.155 : Uranus & Neptune topocentric pos.
