Concordia Research Station, Dome Circe, Antarctic Plateau, Antarctica

Concordia Research Station, Dome Circe, Antarctic Plateau, Antarctica

Writing in the Proceedings of the Astronomical Society of the Pacific, Karim Agabi et al. discuss the suitability of the site for astronomy in terms of the seeing. Their key finding:
The median seeing measured with a DIMM (Differential Image Motion Monitor) placed on top of an 8.5 m high tower is 1.3±0.8 arcseconds.
This is significantly worse than most major observatory sites, but similar to other observatories in Antarctica. However, Lawrence et al. consider other features of the site and conclude that "Dome C is the best ground-based site to develop a new astronomical observatory". Note however that this was written before whole-atmospheric seeing measurements had been made at Dome C.
The experiments to measure the astronomical conditions at the site were controlled by a computer system that had to supervise the generation of its own electricity using a jet-fuel powered stirling engine. The computer, running Linux, communicated with the outside world using an Iridium phone.
