Recent data have shown that Dome C, on the Antarctic plateau, is an exceptional site for astronomy, with atmospheric conditions superior to those at any existing mid-latitude site. Dome C, however, may not be the best site on the Antarctic plateau for every kind of astronomy.
The brightness of the night sky at an astronomical site is one of the principal factors that determine the quality … of available optical observing time. At any site the optical night sky is always brightened with airglow, zodiacal … light, integrated starlight…
Profiling the ground layer turbulence for daytime seeing applications using an array of photodiodes has been documented … in literature, in particular by Beckers who coined the term “SHABAR” for the instrument, short for Shadow Band … Ranger.
The Gattini cameras are two site testing instruments for the measurement of optical sky brightness, large area cloud … cover and auroral detection of the night sky above the high altitude Dome C site in Antarctica. The cameras have been in … operation since January 2006.
We present low-resolution turbulence proles of the atmosphere above Dome C, Antarctica, measured with the MASS instrument during 25 nights in March { May 2004. Except for the … lowest layer, Dome C has signicantly less turbulence than Cerro Tololo and Cerro Pachon. In … particular…
The recent discovery of exceptional seeing conditions at Dome C, Antarctica, raises the possibility … of constructing an optical observatory there with unique capabilities. However, little is known from an astronomer’s … perspective about the optical sky brightness and extinction at Antarctic sites.
To properly characterize the atmospheric properties of a site for a future large telescope or interferometer, it is insufficient to … measure quantities, such as the full-width at half-maximum of a stellar image, that have been integrated over the entire … atmosphere.
