Figure: The automatic and robotic Hertzsprung SONG telescope at Observatorio del Teide. Residuals of the observed radial velocity of Errai (gamma Cephei) for almost 90 consecutive days (upper box) were obtained during autumn 2014. The one day zoom shows clearly the stellar oscillations. Each data point is determined with a precision better than 2 m/s.
