The three Antarctic Survey Telescopes (AST3) aim to carry out time domainimaging survey at Dome A, Antarctica. The first of the three telescopes(AST3-1) was successfully deployed on January 2012. AST3-1 is a 500\,mmaperture modified Schmidt telescope with a 680\,mm diameter primary mirror.AST3-1 is equipped with a SDSS $i$ filter and a 10k $\times$ 10k frame transferCCD camera, reduced to 5k $\times$ 10k by electronic shuttering, resulting in a4.3 deg$^2$ field-of-view. To verify the capability of AST3-1 for a variety ofscience goals, extensive commissioning was carried out between March and May2012. The commissioning included a survey covering 2000 deg$^2$ as well as theentire Large and Small Magellanic Clouds. Frequent repeated images were made ofthe center of the Large Magellanic Cloud, a selected exoplanet transit field,and fields including some Wolf-Rayet stars. Here we present the data reductionand photometric measurements of the point sources observed by AST3-1. We haveachieved a survey depth of 19.3\,mag in 60 s exposures with 5\,mmag precisionin the light curves of bright stars. The facility achieves sub-mmag photometricprecision under stable survey conditions, approaching its photon noise limit.These results demonstrate that AST3-1 at Dome A is extraordinarily competitivein time-domain astronomy, including both quick searches for faint transientsand the detection of tiny transit signals.
