The successful operation of the first robotic node of the SONG network at the Observatorio del Teide, has allowed an unprecedented observing campaign (2016-2018) of the high-precision RV of the ”reference” star Arcturus (\alpha Boo): an evolved red giant similar to our future Sun. Although this star has been observed over the past decades, many basics questions remain open concerning its nature, location at the H-R diagram and global parameters (mass, age) as a consequence of the lack of a proper asteroseismic characterization. The analysis of the exquisite data gathered (RV precision < 1.2 m/s per point), has allowed to firmly stablish its long-term variation (period \sim 170 days and amplitude \sim 200 m/s) and the analysis of its eigenmodes spectrum (periods of about 2-days) should allow its proper asteroseismic characterization.
In this contribution, the current state of the analysis and preliminary results and inferences will be presented.
