Abstract
A Doppler imaging analysis of HD 184905 is pre-sented. Based on time series of high resolution and high signal-to-noise ratio observations we have refined vsini and v_rad with the help of synthesis modelling tools. The maps of Mg and Si abundance distributions were obtained with the help of Doppler imaging software, which was done for the first time for this particular object.
