Scientific paper

UBVRI photoelectric photometry was obtained in the field of the open cluster Tr 18. From the analysis of the data it is confirmed that several distant OB stars were wrongly assumed as cluster members in previous investigations. The true distance modulus of the cluster is 10.95 equivalent to a distance of 1550 pc with the adopted age of (9.0 + or - 1.0) x 10 to the 7th yr. The GH Carinae Cepheid variable star is very much probably a cluster member in view of its spatial position and the average absolute magnitude. However, some arguments are given to suggest that the reality of this cluster is still an open question.
