Scientific paper

The authors have performed digital speckle interferometric observations of Eta Carinae at λ ≡ 820 nm and λ ≡ 850 nm with the 3.6-m and 2.2-m telescope at ESO. Four starlike components (stars or gas clouds) were resolved for the first time. The diameter of all 4 components is <0arcsec.03. The field size of the reconstructed autocorrelation is ≡0arcsec.8. The separations of the components A2, A3 and A4 relative to the brightest component A1 are 0arcsec.18, 0arcsec.22 and 0arcsec.09, respectively.
