Site testing in summer at Dome C, Antarctica
Abstract
We present summer site testing results based on DIMM data obtained at Dome C, Antarctica. These data have been collected on the bright star Canopus during two 3-months summer campaigns in 2003-2004 and 2004-2005. We performed continuous monitoring of the seeing a nd the isoplanatic angle in the visible. We found a median seeing of 0.54 and a median isoplanatic angle of 6.8 . The seeing appears to have a deep minimum around 0.4 almost every day in late afternoon.
