We report redshift measurements of 5 X-ray emitting blue stellar objects(BSO's) located less than 12 arc min from the X-ray Seyfert galaxy, NGC 3516.We find these quasars to be distributed along the minor axis of the galaxy andto show a very good correlation between their redshift and their angulardistance from NGC 3516. Moreover the redshifts of these 5 quasars are: 0.33,0.69, 0.93, 1.40 and 2.10 which are very near the peaks of the redshiftperiodicity distribution (i.e. z=0.3, 0.6, 0.96, 1.41 and 1.96). All theseobserved properties strikingly confirm, around this single example of aSeyfert, the composite picture derived from previous physical associations ofquasars with low redshift, active galaxies.Comment: 10 pages, 3 figures; accepted for publication in Ap
