We report an uncertainty evaluation of an optical lattice clock based on the 1S03P0 transition in the bosonic isotope 174Yb using magnetically induced spectroscopy. The uncertainty due to systematic effects has been reduced to less than 0.8Hz, which represents 1.5 x 10-15 in fractional frequency. The absolute value of the 1S03P0 transition has also been determined through comparisons with optical and microwave standards at NIST. The weighted mean of the evaluations is Ņ(174Yb) = 518 294 025 309 217.8(0.9)Hz. This represents the first step toward the realization of an accurate optical lattice clock based on even isotopes of Yb.
