Today's CometWatch entry was taken by Rosetta’s NAVCAM taken on 18 October 2015, at 433 km from the nucleus of Comet 67P/Churyumov-Gerasimenko.
The scale is 36.9 m/pixel and the image measures 37.8 km across. The contrast was increased to reveal the comet's activity, showing the glow of outflowing material from various regions on the nucleus.
In this view, the comet is oriented with the small lobe on the left and the large lobe on the right. Visible on the small lobe are parts of the Hatmehit, Maftet and Ma'at regions and, towards the centre of the image, the small regions of Nut and Serqet. Hints of the Anuket and Hapi regions can be seen on the comet's neck, while the large lobe presents the circular features of Seth alongside the smooth terrains of Anubis and parts of the complex Atum region.
