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 
mag in the area
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 
magnitudes of all the stars in the investigated
area was compiled. The selection of the cluster members within the
region of 
from the center of the cluster was made.
Altogether, 148 stars were considered to be cluster members by
both astrometrical and photometrical criteria. We present the
estimated age (
yr) and physical parameters of the
cluster and append the catalogues of the proper motions and of the
photometry of the stars.
Key words: open clusters and associations: individual: Trumpler 2
