An analysis of the radial distribution of ab-type RR Lyrae star periods in the outer region of the globular cluster M 3 at has been performed. That analysis points towards a real shortage of stars with long periods in the radial distance range 3.5′ to 6′ (or about 7 to 12 core radii). A brief discussion is presented. The origin of the phenomenon remains an open question.
