Resumen:
We are carrying out a spectroscopic monitoring of Galactic Wolf-Rayet stars, in order to detect binary systems. The sample consists of approximately 50 stars of the Nitrogen sequence (WN) and fainter that V = 13. The observations are made from the 4-m telescope atCTIO, Chile. In the following, we present the first results of the 2007-2008 campaign.
