Evolution of the ejecta morphology seen from white light images in WFM at different dates. Panels c–f include insets showing almost simultaneous images in NFM using adaptive optics. All images are oriented north up and east left. Intensities are in units of 10⁻²⁰ erg s⁻¹ cm⁻². The ellipses indicate the position of the clumps referred to in the text. The green arrows indicate the spirals mentioned in the text. The direction of the Sun and a scale bar are shown in each panel.
