		| Abstract: | 
		The discovery of a new very early O-type binary, LSS 3074 is reported, and a preliminary orbital solution is presented. The spectral classification of the binary components, namely 04f+ and 06-7:(f):, makes LSS 3074 one of the systems with earliest components known in the Galaxy. |
