Azimuthal profile of the brightness intensity for the dust coma of the comet 67P on Feb. 23 (solid line) and March 12 (dashed line) as averaged between the optocentre and 51.5′′. The change of the dust coma morphology and of the intensity of the structures from almost perihelion to post-perihelion on March 12. The structure at a position angle of 80° is more pronounced in the post-perihelion than during closest distances to the Sun. On the other hand, the dust tail shows slightly less intensity after the perihelion.
