International audience We report first results from the CHinese Exoplanet Searching Program fromAntarctica (CHESPA)---a wide-field high-resolution photometric survey fortransiting exoplanets carried out using telescopes of the AST3 (AntarcticSurvey Telescopes times 3) project. There are now three telescopes (AST3-I,AST3-II, and CSTAR-II) operating at Dome A---the highest point on the AntarcticPlateau---in a fully automatic and remote mode to exploit the superb observingconditions of the site, and its long and uninterrupted polar nights. The searchfor transiting exoplanets is one of the key projects for AST3. During theAustral winters of 2016 and 2017 we used the AST3-II telescope to survey a setof target fields near the southern ecliptic pole, falling within the continuousviewing zone of the TESS mission \citep{Ricker10}. The first data release ofthe 2016 data, including images, catalogs and lightcurves of 26578 bright stars($7.5\le i \le15$) was presented in \citet{Zhang18}.
