ADC_Keywords: Stars, giant ; Spectroscopy ; Abundances Abstract: Table2 contains the results of an analysis of elemental abundances in the atmosphere of eta Ser - a red giant of spectral type K2IIIabCN1. The resulting atmosphere parameters correspond to a K0 giant, and the peculiarities of the star chemical composition provide evidence that the assignment of Eta Ser to a class of CN stars was erroneous.
