Discovery of high-quality daytime seeing windows at the Antarctic Taishan station
ABSTRACT We report on the initial results of seeing measurements at the Antarctic Taishan Station (ATS) using a differential image motion monitor observed in the visible at a height of 2.5 m above the snow surface, during the site-testing experiments carried out on 2014 January 13 and 15. The median...
