A photometric analysis of the Cepheus OB3 region Results are presented on Stromgren-Crawford uvby-beta photometry carriedout at Calar Alto (Spain) for 45 stars in the Cepheus OB3 regioncovering an apparent area of 6 deg x 6 deg. The relationship of thesestars with the association is examined. Three of these stars (BD +62 deg2114, BD +62 deg 2152, and BD +62 deg 2156) are identified as members ofthis association, while two more (BD +64 deg 1714 and BD +64 deg 1717)are classified as possible members. It is noted that intrinsic colorsand absolute magnitudes of member stars are consistent with thehypothesis of Blaauw (1964) and Garmany (1973) of the existence of twosubgroups with different evolutionary phases.
