Abstract. Auroral displays are the visible manifestation of the solar wind-magnetosphere-ionosphere interaction at the high latitude polar regions. The study of this phenomenon is very relevant for both the investigation of the magnetosphere-ionosphere coupling and the comprehension of the overall magnetospheric dynamics during the so-called magnetic substorms. Here, we present some preliminary results on the morphological features of the auroral emission as observed at the Mario Zucchelli station in Antarctica during a recent winter campaign. In particular, we are going to show how the morphology of the auroral emission changes with the wavelength (630.0 nm, 557.7 nm and 427.8 nm).
