Title THE CONCORDIA STATION ON ANTARCTICA PLATEAU: THE BEST ASTRONOMICAL SITE IN THE WORLD?
The Nice University involvement, present and future.
Abstract

At 75ºS and on 3250 m of ice thickness, the new italo-french Concordia station will be open for winterover next year, in 2005. This site is the world capital of negative superlatives: temperature, cloud cover, humidity, wind speed are the lowest on our planet, and consequently, coronal skies, IR transparency and astronomical seeing are the best you can find on the same planet! The Nice university astronomers (L.U.A.N.) has already organised 4 "summer" site testing campaigns, and measured seeing parameters as incredible as 0.1 arcsec at best in the visible, or 1 complete second for the time constant. We will describe the site, the site testing campaigns, the main results with real numbers and the main prospects as they develop by now. We will also explain the political situation regarding the possible important development of astronomy in this end-of-the-world place, and the intention of expanding the italo-french cooperative frame to a broader european structure, and very probably even much more. The Jupiter seismology programme "SYMPA" for which we are here observing at the 1.5 m Izaña telescope, is part of the prospects at Concordia for 2007 and later. We will also briefly describe this programme. SYMPA means "Sismometre Interferentiel Imageur Monobloc a Prismes Acoles". It's an instrument dedicated to Jovian oscillations measurements, a sort of natural extension of helioseismology, a science well known at IAC. And of course, you will see nice pictures of the trip to Antarctica, with icebergs, penguins, and again much more....
