  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 uHz has been
determined and twenty-three individual frequencies have been identified.
