Duty Cycle of Doppler Ground‐based Asteroseismic Observations
International audience We report the observations of the clear-sky fraction at the Concordia station during winter 2006 and derive from it the duty cycle for the astronomical observations. The duty cycle and observation duration at Dome C allow for efficient asteroseismic observations. This performa...

International audience We report the observations of the clear-sky fraction at the Concordia station during winter 2006 and derive from it the duty cycle for the astronomical observations.
