We present summer site testing results based on DIMM data obtained at Dome C, Antarctica. These data were 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 and 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.
Key words: site testing
