We have identified the atomic species present in the spectrum of the CP star HR 8137 (HD 202671 = 30 Cap.). We have used spectrograms with a dispersion of 16.9 Å/mm. We also derived log(g) and Teff for the atmosphere of the star using a Kiel diagram. We used UBV and ubvyβ photometry and the profiles of Hydrogen lines. We found Teff = 13250 K and log(g) = 3.1. Adopting these parameters we have derived the abundances of the chemical elements using the WIDTH and ATLAS codes. This star was identified as a Mn CP star however we found a normal abundance of Mng and Ti.Asociación Argentina de Astronomí
