The results of a complex study of the galactic open cluster Trumpler 2 are presented. In order to obtain the proper motions; the positions of approximately 3000 stars up to the limit magnitude B ∼ 16.25 mag in the area 80′ × 80′ around the cluster were measured on 6 plates with a maximal epoch difference of 63 years. The root-mean error of the relative proper motions is 4.2 mas yr-1. The catalogue of BV magnitudes of all the stars in the investigated area was compiled. The selection of the cluster members within the region of R 7 yr) and physical parameters of the cluster and append the catalogues of the proper motions and of the photometry of the stars. © ESO 2006;
