Abstract: We present a comparison of the high-resolution FUV spectrum of Alpha Cen A (G2 V) acquired by STIS on HST with the solar FUV spectra acquired by SUMER on SOHO, and by UVSP on SMM, respectively. We compare the line properties of the strongest lines, and discuss the main peculiarities of the FUV emission of both stars.
