Fig. A.2

Ten WAC images from a sequence acquired on 10 September 2014 from a distance of 29 km and a sub-spacecraft latitude of +48°. The sequence shows the diurnal variation of activity over 9 h (72%) of nucleus rotation. Each view is separated from the previous one by about 1 h (30° of nucleus rotation). The Sun and the comet’s north pole are pointing up in these images. Brightness levels are stretched linearly to emphasize the 5% least bright pixel values.
