Due to the different attraction of Jupiter on the individual comet fragments because of their different distance from the planet, they have now moved so far away from each other that the entire train is too extended to be seen in one frame. It is seen at the upper left of the picture. At the moment of the exposure, fragment A was almost exactly 5 million kilometres from the planet.
North is up and East is to the left.
The broad and diffuse ring, visible around the center of the photo, is an artefact of this process. Image processing by Olivier Hainaut. It may be reproduced, if credit is given to the European Southern Observatory.
