Add to ORKGAlready suspected to be variable, the O9Ib((f)) supergiant HD 152249 has been the subject of a dedicated follow-up spectroscopic run. We report here on the preliminary results. This star is definitely exhibiting significant line-profile variations which are most probably a sign of the existence of non-radial pulsations. HD 152249 could thus belong to the newly identified group of pulsating OB supergiants.status: submitte
