Abstract
Wavelength measurements and line identifications from the 0.14 angstro m/pixel echelle spectra of FG Sge secured two weeks before the drastic dimming of the star in 1992 are presented. The abundances of 18 eleme nts are derived. These abundances have not changed since 1986. Main fe atures of the chemical composition of the FG Sge atmosphere are deplet ion of iron-group elements and marked overabundances (up to 3 dex) of the s-process elements. First time in the observational history of FG Sge C2 Swan bands are identified in its spectrum.
