In this study we use preliminary atmospheric parameters for the A0 Ib supergiant $\eta$ Leo ($T_{\rm eff}, \log g$ and microturbulent velocity) to provide initial estimates of the elemental abundances from S II, Ti II, Cr II, Fe I and Fe II lines by using spectrograms with a two pixel resolution of 0.072 Å and signal-to-noise ratio $\ge$ 200 taken at the Dominion Astrophysical Observatory.To search for other articles by the author(s) go to: http://adsabs.harvard.edu/abstract_service.html
