Representative images of T-G-K in the CN (right column) and R-band (left column) filters throughout the 2017 apparition, following enhancement as described in Section 2.2. Brighter regions are shown as yellow or white. Date and mid-time are given on each image, and the direction of the Sun is indicated by an arrow; each image is 30,000 km on a side, and star trails are often visible. One or two CN features are evident throughout the apparition, often appearing as clockwise rotating partial spirals, and the near-disappearance of the jets in the anti-sunward hemisphere strongly suggests that the source regions mostly shut off at night. As expected, the R-band images show a strong dust tail but also sometimes exhibit a fainter near-linear feature somewhat offset from the sunward direction. Overall, the long-term trends appear to be simply caused by changing viewing geometries.
