We present the results of near continuous TESS optical observations of theasynchronous polar CD Ind (RX J2115-5840). The 27.9 d long light curve, with 2min resolution, reveals remarkable changes in the magnetic accretion geometryof the system over the 7.3 d beat period. We have modelled the changes in theoptical spin period pulse shape using a cyclotron emission mapping technique.The resulting cyclotron emission maps of the magnetic white dwarf reveal howthe accretion geometry changes from single to two pole accretion and back overthe beat cycle. Finally, we present the results from particle based numericalmagnetic accretion simulations, that agree with our interpretation of thechanging accretion scenario.
