Abstract: The F5 subgiant Procyon A (alpha CMi, HR 2943) was observed with the CORALIE fiber-fed echelle spectrograph on the 1.2-m Swiss telescope at La Silla in February 1999. The resulting 908 high-accuracy radial velocities exhibit a mean noise level in the amplitude spectrum of 0.11 m s(-1) at high frequency. These measurements show significant excess in the power spectrum between 0.6-1.6 mHz with 0.60 m s(-1) peak amplitude. An average large spacing of 55.5 muHz has been determined and twenty-three individual frequencies have been identified.
