We present the uvbyβ data used to locate the dust and derive distances for nearby diffuse interstellar clouds in the EUV shadows lb27-31, lb165-32 and lb329+46 discovered by the Extreme Ultraviolet Explorer. The photometrically derived parallaxes of our program stars are compared to the parallaxes listed in the Hipparcos Catalog. Within the photometric distance limit of 150pc, the photometric parallaxes of 21 ``normal" stars are consistent with the Hipparcos measurements within an uncertainty of 15%. Much as expected for the Stroemgren system. Since all program stars are brighter than V≃11.5 most of them are included in the Tycho photometry. For our sample of ∼200 stars we find V_by and V_T to be consistent. Few stars are common to published uvbyβ catalogs, ∼10, V and the indices compare well apart from β where a zero point difference of 11mmag is noticed.
