| Abstract: | The positions of Uranus were observed astrometrically with a CCD detector attached to the Pulkovo Normal astrograph (D/F = 0.33 m/3.5 m, S2C CCD, FOV 18′ × 16′). We provide the positions in the time interval from 2006 to 2011. Reduction of the CCD images was made with reference to the UCAC3 catalogue. The (O-C) values were calculated using the “Natural Satellites Service”. The results were compared with two contemporary theories of Uranus’s motion: INPOP10 and DE414/LE414. The obtained equatorial coordinates correspond well to both theories. On average, (O-C) over both coordinates relative to both theories are 0.1″. |
