Figure 5d sums Figure 5c spectrally; the time series of the full sum over all wavelengths (thin line) shows two peaks corresponding to auroral oval crossings
Figure 8 schematically illustrates the regions that we will now discuss: the UV ‐ dark polar hexagon, the sur- sur-rounding dark collar, the bright but narrow main auroral oval just outside the hexagon, and the sursur-rounding broader diffuse aurora that p
Figure 7. To better show the full hexagon, known to rotate at near the planetary rate, Cassini UVIS data from 23 January 2017 (day 23) 8:54 – 10:16 obtained in two side ‐ by ‐ side 40 ‐ min slews across the north polar region have been reprojected into a p
