We have conducted a campaign of observations in May and October 1999 of the Uranian system wit the ADONIS AO system mounted on the ESO 3.6m telescope.Among other satellites of Uranus, Puck, the outermost one of the satellites discovered by Voyager 2 in July 1986 is detected on all our images. The correction of atmospheric turbulence by the AO system is stable and provides a satisfactory signal to noise ratio. In order to improve the accuracy of the satellite position determination (up to 30 mas), we had defined a Moffat-Gauss function. We determine the orbital parameters by a least square fit method and we discuss possible interpretations. Data presented here are based on observations collected at the European Southern Observatory, Chile (proposal: 66.C-0707).
