Resumen

Determination of atmospheric parameters of the lensed star was discussed. High resolution spectra of a magnified bulge star were obtained at the 8 m Kueyen VLT-UT2 telescope with the UVES spectrograph. Oxygen abundances were estimated by taking into account the molecular dissociation equilibrium. Stellar parameters of effective temperature, gravity log, reddening and metallicity were derived from the data.
