We report Doppler measurements of Cen A from time-series spectroscopy made with two spectrographs: UCLES at the 3.9-m AAT (data fully reduced) and UVES at the 8.2-m VLT (data reduction in progress). Wavelength calibration using an iodine absorption cell produced high-precision velocity measurements, whose power spectrum shows the clear signature of solar-like oscillations, confirming the detection reported by Bouchy & Carrier (2001).
