The optical spectra of Luminous Blue Variables (LBV’s) are characterized by strong Balraer emission lines. In many cases, the narrow emission component (FWHM ≤ 300 km/sec) shows extended emission wings reaching up to -1000 km/sec. These wings are generally attributed to electron scattering of line photons in the dense stellar wind (Bernat and Lambert 1978). In this paper we discuss an alternative mechanism which may partly contribute to the observed line wings.
