Abstract
The authors have proposed in previous works, that the star #3 in the open cluster Trumpler 14 displays double lines in its spectrum. They believe that this is due to the binary nature of this object. The authors have also discussed in previous papers the importance of determining the incidence of binary systems in clusters as young as Trumpler 14. Here they report the progress made in the observation of Tr 14 #3, in a project devoted to determining the period and orbital elements of this binary system. The authors have obtained so far 12 new spectrograms of the star Tr 14 #3 which have been measured for radial velocities. Among them, they found 8 on which the radial velocities of the primary and secondary components can be derived.
