A catalogue of 1192 galaxies in the central regions (30' x 30') of 11 clusters in the Ursa Major supercluster is presented. For each galaxy equatorial and relative coordinates and total B and R_c_ magnitudes and B-R_c_ colour are given. Plates taken with the 2-m Tautenburg Observatory telescope and CCD images obtained with the 6-m and 1-m SAO telescopes are used.
