The statistics and dynamics of the atmospheric seeing at the South Pole have been studied over a period of 101 days in
winter. These measurements have been made with the first fully
autonomous differential image motion monitor, the A-DIMM. The analysis shows
an average seeing of 
with a standard
deviation of 
. The extensive set of data has allowed the study of the seeing time variations,
showing that the seeing varies by a factor of two within a characteristic time of 2 hours.
