Abstract
Coudé spectroscopic data of a poorly-studied peculiar supergiant, HD 327083, are presented. H$\alpha$ and H$\beta$ line profiles have been fitted employing a non-LTE code adequate for spherically expanding atmospheres. Line fits lead to estimates of physical parameters. These parameters suggest that HD 327083 may be close to the Luminous Blue Variable phase but it is also possible that it could be a B[e] Supergiant.
