The field of view of this portion of the image is approx. The Comet was at 1.18AU from the Sun and 1.68AU from Earth.
North is up and East is Left.
The main jet is pointing toward the Sun. What is seen are multiple jets of material emanating from the near-nuclear region. As active regions move into and out of sunlight the escaping material can form concentric shell-like structures. Once the dust leaves the surface of the comet, it quickly no longer feels the gravity from the nucleus and the dust grains move in their own orbits around the sun, and much of the curvature can be explained by the radiation pressure from the sun pushing the dust tailward. The structures in the inner coma of comets are a very complex combination of the position of the active vents outgassing material, the velocity at which the material leaves, the rotation of the nucleus, the sun's radiation pressure and any secondary sources of material - such as dust in the coma.
