Abstract
High resolution spectra of a magnified bulge star were obtained at the 8 m Kueyen VLT-UT2 telescope with the UVES spectrograph. The source is a bulge giant of baseline magnitude $V_{\rm EROS} = 18.4$, magnified to $V \approx 18.0$. These data allow us to derive the stellar parameters of effective temperature $T_{\rm eff} \sim 3800$ K, gravity log  $g \sim 1.0$, reddening $E(B-V) \sim 0.7$, metallicity and and [O/Fe] $\approx$ 0.0 for EROS-BLG-2000-5. The giant appears to be located in the far side of the bulge.
