Spectra of [O III] nebular and auroral lines on day 822 post-discovery. The observed line profiles (blue-solid lines) were used in the fitting of a morpho-kinematical model with the SHAPE software, seen as the overlaid black dots. The auroral line is fitted with an equatorial disk whereas the nebular lines fit an equatorial waist and polar cones morphology with a Hubble outflow velocity law, see Fig. 8.
