Caption: Figure 3.

Representative CN images from every night of observation throughout T-G-K’s apparition. Up to four images are presented each night to show the rotational motion. Note the slow progression of the peak brightness of the jets as they follow the Sun’s PA (arrows), implying that peak brightness is always near local noon, and other bulk changes with our viewing geometry, but that no abrupt changes in morphology are evident. Scaling is the same as in previous figures.
