Abstract: The SONG spectrograph has recently demonstrated its ability to perform solar radial velocity measurement during the first test run of the Solar-SONG initiative. A preliminary assessment of its performance is carried out here by comparing the results of Solar-SONG during the summer 2018 test run, with GOLF and VIRGO/SPM taken as reference instruments.
