This has two interesting consequences. First, two full rotations of the nucleus are only slightly less than one day, so we see a similar point in the rotation each night. This makes the jets and the shells appear to move only very slowly from night to night. The second consequence is that, on some nights, where we have as much as 2 hours of data, this is a significant part of the rotation period of the nucleus. This rotation somewhat blurs the structures that we see.
Diagonal streaks cross some of the frames from top right to lower left.
These are just star trails. This is the start of the ion tail and can only be seen in a very few images. Some frames, such as frame 10, show some very complex structures in the inner shell. Here we see the spirals from the two jets not quite overlapping and, as a result, producing some complicated interactions. This shows that the two active areas are probably not quite separated by 180 degrees on the nucleus, although they are close being exactly on opposite sides.
