Abstract

The astronomical seeing from the Antarctic high plateau site Dome C has been a matter of speculation for over a decade. During 2004 we made the first wintertime measurements of the seeing using a Multi Aperture Scintillation Sensor (MASS), a device that is well-suited for automated unattended operation. The mean seeing was found to be 0.27 arcsec, and the seeing is better than 0.15 arcsec for 25% of the time. These extraordinarily low levels of turbulence make Dome C a superb site for future optical and infrared telescopes.
