Abstract: We have obtained uvby data for 51 stars in the region of the association Lacerta OB1, near the O9 V star 10 Lac. An analysis of the present data, combined with previous observations by others, leads to an average color excess for the more concentrated of the two subgroups (1b) of (E(b - y)) = (one ) and an average distance modulus of V0 - Mv fi = i (one star). The more dispersed subgroup has a larger average excess and a larger dispersion in both color excess and distance modulus for the stars. Several stars are suggested as nonmembers. Key words: photometry - stellar association - color excess
