Corrections to Newcomb’s lunisolar precession and to motion of the equinox are evaluated from proper motions of 77 Cepheids, employing recently determined values of their distances. Results are diverse, depending on the weighting method. If the effect of the cosmic dispersion is neglected and ω0 is imposed to be 25 km/s/kpc, then Δp1 = 1.″1 ±0.″2 and Δλ′ + Δe = 1.″0 ±0.″1 per century in the FK4 system.
