Scientific paper

Spectrographic observations of the object Sk-71 deg 34 made using a Cassegrain image-tube spectrograph on the 4-m telescope at Cerro Tololo with a baked IIIa-J emulsion and a dispersion of 47 A/mm are reported. The object, originally classified as OB(e) by Sanduleak (1969) is found to consist of two stars and is classified as type WN3+O4, a relatively weak-lined Wolf-Rayet star of the N sequence accompanied by a normal O4 star. The possible reasons for its earlier nondetection are discussed, and similarities to the nearby object Sk-67 deg 22 are pointed out.
