13 people (six French, five Italian, one Russian and one Greek): Bruno Limouzy: Electrical motors, Giorgio Deidda: Chef, Tindari Ceraolo:physician, Adrianos Golemis: ESA biomedical research, Pierre Pejoine: Mechanic, Paride Legovini: Physicist, Electronic technician for science, Julien Ribet: Electrotechnician, Tommaso Nicosia: Computer, telecommunications, Daniele Tavagnacco: Astrophysicist, Olivier Haye: Technical Chief, plumbing and heating, Cecile Lenormant: Chemist, Igor Petenko: Atmospheric science and climate, Xavier Joffrin: Astronomy, . During the 2014 Antarctic winter Concordia was an active amateur radio station: Paride Legovini operated from there on a weekly basis with call sign IA/IZ3SUS. The HF radio equipment consists in a Rohde & Schwarz XK2100L transceiver with a 150W RF output and a delta loop antenna located a few hundreds of meters away from the station. The analemma (path that the sun follows in the sky if photographed at precisely the same time every week through the course of a year) was imaged for the first time ever in Antarctica by Adrianos Golemis during the 10th winterover mission at Concordia Station (2013–2014). The resulting composite exposure image was selected as NASA Astronomy Picture of the Day (APOD) on 23 September 2015. Eleventh winter-over (DC11 – 2015) The eleventh wintering is taking place from February 2015 to November 2015 with a team of 13 people (six French, five Italian, one British and one Swiss): Mario Salza: Station Leader, Information and Communications Technology (ICT), Yannick Marin: Technical Manager and Electrical motors, Antonietta Roveran: Physician, Roxanne Jacob: Glaciology and Atmospheric Chemistry, Luca Ficara: Chef, Guillaume Poirot: Mechanic, Giampietro Casasanta: Glaciology and Atmospheric Remote Sensing, Benoit Laurent: Electronics for Science, Markus Wildi: Astrophysics, Benoit Joncheray: Plumbing and Heating Engineering Technician, Lorenzo Moggio: Atmospheric physics, Beth Healey: ESA Biomedical Research, Rémi Puaud: Electrical Engineering Technician, Twelfth winter-over (DC12 – 2016) The twelfth winter began on February 10, 2016, with twelve overwintering (five Italian, six French, one Dutch): Elvio Lazzarini: Physician, Alessandro Fausto: Information and Communications Technology (ICT), Luciano Milano: Electronics for Science, Vitale Stanzione: Station Leader, Glaciology, Bertrand Bonnefoy: Chef, Floris van den Berg: ESA Biomedical Research MD, Georges Karakasidis: Electrician, Henri van den Hove: Plumbing and Heating Engineering Technician, Olivier Leloir: Technical Chief, Gaetan Quere: Mechanic, Simonetta Montaguti: Atmospheric Science and Climate, Nicole Hueber: Glaciology and Atmospheric Chemistry, Thirteenth winter-over (DC13 – 2017) The thirteenth winter began on February 9, 2017, with thirteen overwintering (five French, seven Italian, one Belgian Canadian): Simone Chicarella: Electronics for Science, Station Leader,
