Based on a sample of more than 145000 stars at distances $r<0.5$~kpc, we have found the following kinematic parameters:\n  (U,V,W)_\\odot=(9.12, 20.80, 7.66)\\pm(0.10, 0.10, 0.08) km s^{-1},\n  \\Omega_0=28.71\\pm0.63 km s^{-1} kpc^{-1}, and\n  \\Omega'_0=-4.28\\pm0.11 km s^{-1} kpc^{-2}. This gives the linear rotation velocity V_0=230\\pm12 km s^{-1} (for the adopted R_0= 8.0\\pm0.4 kpc) and the Oort constants A=17.12\\pm0.45 km s^{-1} kpc^{-1} and B=-11.60\\pm0.77 km s^{-1} kpc^{-1}.
