Abstract:
    CCD observations are used to analyse the atmosphere of the G7 IIIa
    giant Eta Piscium. The following atmospheric parameters were obtained:
    T(eff)=4930K, logg=2.1, and microturbulence v(t)=1.7km/s. The
    abundances of 21 elements in the atmosphere of eta Psc were
    determined.
