CometWatch 20 May

This image of Comet 67P/Churyumov-Gerasimenko was taken by Rosetta's NAVCAM on 20 May at a distance of 163.6 km from the comet centre. It is a single frame image with a resolution of 13.9 m/pixel, and measures 14.3 km across. The intensities and contrast have been adjusted to emphasise the activity of the comet. In this orientation, perhaps the most striking observation is the activity seen close to Hatmehit, the circular depression on the comet’s small lobe. There also appears to be activity associated with the Nut region, which lies below Serqet in this orientation. In both cases, the activity stands out against the shadowed portions of the comet in this area. On the large lobe, the comet is oriented with the relatively smooth face of Anubis towards the top left, making a distinct boundary with the neighbouring rugged Seth region to the right. In this view the comet also shows off the transition between the two lobes, with Anuket on the small lobe merging into Hapi at the neck. The original 1024 x 1024 pixel image is provided below:
