Scientific paper

We report spectroscopic observations of a new Wolf-Rayet star not identified yet. This star is located in our Galaxy, in the Canis Majoris region and was discovered during a southern spectroscopic survey of stars previously identified as Hα emission objects. The star, SPH 2, after Schwartz, Persson & Hamann (SPH) (1990), shows the main characteristics of a WN star and a strong CIV 5808 typical of a WC star. Here, we present some of the main spectroscopic features and discuss a possible subtype classification. We also present line intensities and equivalent widths of the identified transitions. Based on observations made with the 1.52m telescope at the European Southern Observatory (La Silla, Chile) under the agreement with the CNPq-Observatório Nacional (Brazil).
