The morphology of the ejected shell of V339 Del (Nova Del 2013) outburst was preliminary studied. The optical spectra from the Liverpool telescope around 80 days after discovery were examined. Synthetic line profile spectra were compared to emission lines of H β in order to find the best-fit morphology of the ejected shell using the programme SHAPE. When adopted an inclination i = 65° and suggested shape of the shell from literature, a simplest preliminary morphology was found to be a bipolar at squeeze parameter around 0.8 - 1 with a torus.
