Abstract
We present Hα spectra of the 35.5 d period Cepheid ℓ Carinae throughout several cycles during 1994 and 1995. A weak Hα emission feature is present at nearly all phases, which is unusual for classical Cepheids. This emission appears both redward and blueward of the absorption feature at different phases.Keywords
