Abstract
The Galactic O-Star Spectroscopic Survey (GOSSS) is a project that is observing all known Galactic O stars with B < 13 (+/-2000 objects) in the blue-violet part of the spectrum with R+/-2500. It also includes two companion surveys (a spectroscopic one at R+/-1500 and a high resolution imaging one). It is based on v2.0 of the Galactic O star catalog (v1, Maíz-Apellániz et al. 2004; v2, Sota et al. 2008). We have completed the first part of the main project. Here we present results on the first 400 objects of the sample.
