Abstract

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 H 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.

Key words: Wolf-Rayet: general Wolf-Rayet: WN stars emission line stars

* 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).
