  We construct the rotation curve of the Milky Way in the extended solar
neighbourhood using a sample of SEGUE (Sloan Extension for Galactic
Understanding and Exploration) G-dwarfs. We investigate the rotation curve
shape for the presence of any peculiarities just outside the solar radius as
has been reported by some authors. We approach the problem in a framework of
classical Jeans analysis. Using the most recent data from RAVE (RAdial Velocity
Experiment), we determine the solar peculiar velocity and the radial
scalelengths for the three populations of different metallicities representing
the Galactic thin disc. Then with the same binning in metallicity for the SEGUE
G-dwarfs, we construct the rotation curve in the range of Galactocentric
distances 7-10 kpc. We derive the circular velocity by correcting the mean
tangential velocity for the asymmetric drift in each distance bin. With SEGUE
data we also calculate the radial scalelength of the thick disc taking as known
the derived peculiar motion of the Sun and the slope of the rotation curve. The
rotation curve constructed through SEGUE G-dwarfs appears to be smooth in the
selected radial range. The local kinematics of the thin disc rotation as
determined in the framework of our new careful analysis does not favour the
presence of a massive overdensity ring just outside the solar radius.
