Abstract
In parallel with the monitoring of the periastron passage of the binary system WR 140, a number of B supergiants and Oe stars have been observed in the framework of a 4-month spectroscopic run using the Mons telescope at Teide observatory. We expose the motivations behind this campaign, present an overview of the Halpha variations exhibited by the B supergiants and finally briefly discuss forthcoming developments in the data analysis.
