Resumen:
Using the 2.15-m telescope at CASLEO we obtained spectroscopic observations of the star identified as number 15 by Forte & Orsatti 1981 (AJ 86, 209) located in the field of NGC 3372 in the Carina region. We found that this star, which we classified as O5V, is a spectroscopic binary with a period of 3.38 days. Preliminary orbital elements were derived from the radial velocity curve analysis.
