Abstract
By means of spectrographic observations obtained at CTIO, Chile, we ha ve determined that HDE 320102 is an O6+WN binary system, with an orbit al period of 12.595 days. We present an analysis of the orbital elemen ts of this system based on radial velocities of the absorption lines o f the O6 component, and of the He II lambda 4686 and N V lambda lambda 4603-19 emissions of the WN component.
